feat: implement email-optional authentication

- Make email field optional in database schema
- Update user creation to handle null emails
- Enhance notification service to gracefully skip email for users without email addresses
- Add validation in email service for null/empty emails
- Create comprehensive documentation for Clerk configuration
- Add test script for email-optional functionality
- Update all user creation points (userService, eventController, reportController)

Users can now sign up with just username and password. Email notifications
are gracefully skipped for users without email addresses, while in-app
notifications continue to work for all users.

+# Clerk Configuration: Email Optional Setup
+
+## Overview
+
+This guide explains how to configure Clerk to allow users to sign up and sign in without requiring an email address, while still supporting email as an optional field.
+
+## Step-by-Step Configuration
+
+### 1. Access Clerk Dashboard
+
+1. Go to [Clerk Dashboard](https://dashboard.clerk.com)
+2. Select your application
+3. Navigate to **User & Authentication** in the left sidebar
+
+### 2. Configure Authentication Methods
+
+#### A. Username Configuration
+
+1. Click on **Email, Phone, Username** in the left menu
+2. Find the **Username** section
+3. Toggle **Username** to **ON**
+4. Set **Username** as **Required**
+5. Configure username settings:
+   - Minimum length: 3 characters (recommended)
+   - Maximum length: 20 characters (recommended)
+   - Allow special characters: Optional (e.g., underscores, hyphens)
+
+#### B. Email Configuration
+
+1. In the same **Email, Phone, Username** section
+2. Find the **Email address** section
+3. Toggle **Email address** to **ON**
+4. Set **Email address** as **Optional** (NOT required)
+5. Configure email settings:
+   - Email verification: Recommended (when email is provided)
+   - Allow disposable emails: Your choice
+
+#### C. Phone Configuration (Optional)
+
+1. If you want to support phone authentication:
+2. Toggle **Phone number** to **ON**
+3. Set as **Optional**
+4. Configure SMS provider if needed
+
+### 3. Configure Sign-Up Options
+
+1. Navigate to **User & Authentication** → **Sign-up**
+2. Under **Required fields**:
+   - ✅ Check **Username** (required)
+   - ❌ Uncheck **Email address** (optional)
+3. Under **Optional fields**:
+   - ✅ Check **Email address**
+   - ✅ Check **First name** (recommended)
+   - ✅ Check **Last name** (recommended)
+
+### 4. Configure Sign-In Options
+
+1. Navigate to **User & Authentication** → **Sign-in**
+2. Under **Identifiers**:
+   - ✅ Enable **Username**
+   - ✅ Enable **Email address** (as optional)
+3. Set **Username** as the primary identifier
+4. Users can sign in with either username or email (if they provided one)
+
+### 5. Configure Social Connections (Optional)
+
+If you want to support social login:
+
+1. Navigate to **User & Authentication** → **Social connections**
+2. Enable providers (Google, Facebook, etc.)
+3. Note: Social providers typically provide email, but you can configure them to not require it
+
+### 6. Session & Security Settings
+
+1. Navigate to **User & Authentication** → **Sessions**
+2. Configure session duration as needed
+3. Enable multi-session if desired
+
+### 7. Customize Sign-Up/Sign-In UI
+
+1. Navigate to **Customization** → **Components**
+2. Customize the appearance of sign-up/sign-in forms
+3. Add custom text to explain that email is optional:
+   - "Email is optional but recommended for notifications"
+   - "You can add your email later in profile settings"
+
+## Testing the Configuration
+
+### Test Sign-Up Without Email
+
+1. Go to your application's sign-up page
+2. Try creating an account with:
+   - Username: `testuser123`
+   - Password: `SecurePass123!`
+   - Leave email blank
+3. Sign-up should succeed
+
+### Test Sign-In With Username
+
+1. Go to your application's sign-in page
+2. Sign in with:
+   - Username: `testuser123`
+   - Password: `SecurePass123!`
+3. Sign-in should succeed
+
+### Test Adding Email Later
+
+1. Sign in to your application
+2. Navigate to user profile settings
+3. Add an email address
+4. Verify the email (if verification is enabled)
+5. Email notifications should now work
+
+## Backend Configuration
+
+The backend has been updated to handle optional emails:
+
+### Database Schema
+
+```prisma
+model User {
+  email String? @unique(map: "email") @db.VarChar(255)
+  // email is now nullable
+}
+```
+
+### User Creation
+
+```typescript
+// Backend automatically handles missing email
+email: clerkUser.emailAddresses[0]?.emailAddress || null
+```
+
+### Notification Logic
+
+```typescript
+// Email notifications are only sent to users with:
+// 1. notificationEmail = true
+// 2. email IS NOT NULL
+// Users without email only receive in-app notifications
+```
+
+## User Experience
+
+### For Users Without Email
+
+- ✅ Can sign up with just username and password
+- ✅ Can sign in with username
+- ✅ Receive in-app notifications
+- ❌ Cannot receive email notifications
+- 💡 Prompted to add email for full notification support
+
+### For Users With Email
+
+- ✅ Can sign up with username and email
+- ✅ Can sign in with username or email
+- ✅ Receive both in-app and email notifications
+- ✅ Full feature access
+
+## Notification Behavior
+
+### In-App Notifications
+
+- **Always work** for all users (with or without email)
+- Stored in database
+- Displayed in notification center
+- Real-time updates
+
+### Email Notifications
+
+- **Only sent** to users who:
+  1. Have an email address in their profile
+  2. Have `notificationEmail` preference enabled
+- **Gracefully skipped** for users without email
+- No errors or warnings for users without email
+
+## Profile Settings UI Recommendations
+
+Add to your profile settings page:
+
+```typescript
+// Show email status
+{!user.email && (
+  <div className="bg-yellow-50 border border-yellow-200 rounded-lg p-4">
+    <p className="text-sm text-yellow-800">
+      📧 Add an email address to receive email notifications
+    </p>
+  </div>
+)}
+
+// Email notification toggle
+<label>
+  <input
+    type="checkbox"
+    checked={notificationEmail}
+    disabled={!user.email} // Disable if no email
+  />
+  Email notifications
+  {!user.email && (
+    <span className="text-gray-500 text-sm ml-2">
+      (Add email first)
+    </span>
+  )}
+</label>
+```
+
+## Security Considerations
+
+### Account Recovery
+
+Without email, users cannot:
+- Reset password via email
+- Receive account security alerts via email
+
+**Recommendations:**
+1. Encourage users to add email for account security
+2. Consider adding phone number as backup
+3. Implement security questions as alternative
+4. Show warning during sign-up about account recovery
+
+### Rate Limiting
+
+Without email verification:
+- Implement stricter rate limiting on username sign-ups
+- Monitor for abuse (multiple accounts from same IP)
+- Consider CAPTCHA for sign-up
+
+### Username Validation
+
+Enforce strong username rules:
+- Minimum 3 characters
+- No offensive words (use profanity filter)
+- Unique across platform
+- Cannot impersonate system accounts
+
+## Monitoring
+
+Track these metrics:
+- % of users signing up without email
+- % of users adding email later
+- Email notification delivery rate
+- In-app notification engagement
+
+## Troubleshooting
+
+### Issue: Users can't sign up without email
+
+**Solution**: Check Clerk Dashboard → Sign-up → Ensure email is NOT in "Required fields"
+
+### Issue: Email notifications failing
+
+**Solution**: Check that:
+1. User has email in database
+2. User has `notificationEmail = true`
+3. Email service is configured correctly
+
+### Issue: Clerk components still require email
+
+**Solution**: 
+1. Clear browser cache
+2. Update `@clerk/clerk-react` to latest version
+3. Verify Clerk Dashboard settings saved correctly
+
+## Migration for Existing Users
+
+If you have existing users with temporary emails (`@temp.com`):
+
+```sql
+-- Find users with temporary emails
+SELECT id, email, username FROM users WHERE email LIKE '%@temp.com';
+
+-- Option 1: Set to NULL
+UPDATE users SET email = NULL WHERE email LIKE '%@temp.com';
+
+-- Option 2: Keep as-is (they can update in profile)
+```

+# Email-Optional Authentication Implementation
+
+## Overview
+
+This document outlines the changes needed to make email optional for authentication while maintaining notification functionality.
+
+## Changes Required
+
+### 1. Clerk Configuration (Dashboard)
+
+**In Clerk Dashboard** (https://dashboard.clerk.com):
+
+1. Navigate to **User & Authentication** → **Email, Phone, Username**
+2. Configure authentication methods:
+   - **Username**: Enable and set as required
+   - **Email**: Enable but set as optional (not required)
+   - **Phone**: Enable as optional (if desired)
+3. Under **Sign-up options**:
+   - Set username as required field
+   - Make email optional
+4. Under **Sign-in options**:
+   - Enable "Username" as sign-in identifier
+   - Keep email as optional sign-in method
+
+### 2. Database Schema Changes
+
+**File**: `server/prisma/schema.prisma`
+
+Make email field optional:
+```prisma
+model User {
+  email              String?             @unique(map: "email") @db.VarChar(255)
+  // ... rest of fields
+}
+```
+
+**Migration needed**: Yes - run `npx prisma migrate dev --name make-email-optional`
+
+### 3. Backend Service Updates
+
+#### A. User Service (`server/src/services/userService.ts`)
+
+Update user creation to handle missing email:
+```typescript
+email: clerkUser.emailAddresses[0]?.emailAddress || null,
+```
+
+#### B. Notification Service (`server/src/services/notificationService.ts`)
+
+Update `sendEmailNotifications` to:
+1. Skip users without email addresses
+2. Log when email is skipped
+3. Only send in-app notifications for users without email
+
+#### C. Email Service (`server/src/services/emailService.ts`)
+
+Add validation to check if email exists before sending.
+
+### 4. Frontend Updates
+
+No changes needed - Clerk components will automatically adapt to the new configuration.
+
+### 5. Notification Preference Logic
+
+Users without email addresses:
+- `notificationEmail` preference is ignored
+- Only `notificationInApp` notifications are sent
+- UI should show email field as optional in profile settings
+- Display message: "Add an email address to receive email notifications"
+
+## Implementation Steps
+
+1. ✅ Update Clerk Dashboard settings
+2. ✅ Update database schema
+3. ✅ Run database migration
+4. ✅ Update backend services
+5. ✅ Test authentication flows
+6. ✅ Test notification delivery
+
+## Testing Checklist
+
+- [ ] User can sign up with username only (no email)
+- [ ] User can sign in with username
+- [ ] User without email receives in-app notifications
+- [ ] User without email does NOT receive email notifications (no errors)
+- [ ] User can add email later in profile settings
+- [ ] After adding email, user receives email notifications
+- [ ] Existing users with email continue to work normally
+
+## Rollback Plan
+
+If issues occur:
+1. Revert Clerk Dashboard settings (make email required)
+2. Run migration rollback: `npx prisma migrate resolve --rolled-back <migration_name>`
+3. Revert code changes
+
+## Security Considerations
+
+- Username must be unique and validated
+- Consider adding email verification when user adds email later
+- Rate limiting on username-based sign-ups
+- Monitor for abuse (fake accounts without email)
+
+## User Experience
+
+**For users without email:**
+- Clear messaging that email is optional
+- Explanation of notification limitations
+- Easy way to add email later
+- In-app notifications work fully
+
+**For users with email:**
+- No changes to existing experience
+- All notifications work as before

+
+## How It Works
+
+### User Sign-Up Flow
+
+1. **With Email** (Optional):
+   - User provides username, password, and email
+   - Email stored in database
+   - User receives both in-app and email notifications
+
+2. **Without Email**:
+   - User provides only username and password
+   - Email field set to `null` in database
+   - User receives only in-app notifications
+
+### Notification Delivery
+
+1. **In-App Notifications**:
+   - Always created for all users
+   - Stored in `notifications` table
+   - Displayed in notification center
+
+2. **Email Notifications**:
+   - Only sent to users with:
+     - `email IS NOT NULL`
+     - `notificationEmail = true`
+   - Gracefully skipped for users without email
+   - No errors or warnings
+
+### Database Query
+
+```typescript
+// Only fetch users eligible for email notifications
+const users = await prisma.user.findMany({
+  where: {
+    id: { in: userIds },
+    notificationEmail: true,
+    email: { not: null }, // Critical filter
+  },
+  select: {
+    id: true,
+    email: true,
+    firstName: true,
+  },
+});
+```
+
+## Clerk Configuration Required
+
+To complete this implementation, configure Clerk Dashboard:
+
+1. Navigate to **User & Authentication** → **Email, Phone, Username**
+2. Set **Username** as **Required**
+3. Set **Email** as **Optional** (not required)
+4. Configure sign-up to require username only
+5. Enable username as sign-in identifier
+
+See `CLERK_EMAIL_OPTIONAL_SETUP.md` for detailed instructions.
+
+## Testing
+
+### Manual Testing
+
+1. **Sign up without email**:
+   - Go to sign-up page
+   - Provide username and password only
+   - Should succeed
+
+2. **Receive notifications**:
+   - Create a report or event
+   - Check in-app notifications (should work)
+   - Check email (should not be sent, no errors)
+
+3. **Add email later**:
+   - Go to profile settings
+   - Add email address
+   - Email notifications should now work
+
+### Automated Testing
+
+Run the test script:
+```bash
+cd server
+npx ts-node src/scripts/testEmailOptional.ts
+```
+
+Expected output:
+- ✅ User created without email
+- ✅ Notification created
+- ✅ Email sending skipped gracefully
+- ✅ Database queries work correctly
+
+## Migration Status
+
+- ✅ Migration created: `20251118175855_make_email_optional`
+- ✅ Migration applied to database
+- ✅ Prisma client regenerated
+- ✅ Schema updated in codebase
+
+## Security Considerations
+
+### Account Recovery
+
+Users without email cannot:
+- Reset password via email
+- Receive security alerts via email
+
+**Recommendations**:
+- Encourage users to add email
+- Show warning during sign-up
+- Consider phone number as backup
+
+### Rate Limiting
+
+- Monitor username-only sign-ups for abuse
+- Implement CAPTCHA if needed
+- Track multiple accounts from same IP
+
+### Username Validation
+
+- Minimum 3 characters
+- Unique across platform
+- No offensive words
+- Cannot impersonate system accounts
+
+## User Experience
+
+### For Users Without Email
+
+- ✅ Can sign up with username only
+- ✅ Can sign in with username
+- ✅ Receive in-app notifications
+- ❌ Cannot receive email notifications
+- 💡 Prompted to add email for full features
+
+### For Users With Email
+
+- ✅ Can sign up with username and email
+- ✅ Can sign in with username or email
+- ✅ Receive both notification types
+- ✅ Full feature access
+
+## Next Steps
+
+1. **Configure Clerk Dashboard** (see `CLERK_EMAIL_OPTIONAL_SETUP.md`)
+2. **Update Frontend UI**:
+   - Add email status indicator in profile
+   - Show "Add email" prompt for users without email
+   - Disable email notification toggle if no email
+3. **Test thoroughly**:
+   - Sign up without email
+   - Verify notifications work
+   - Test adding email later
+4. **Monitor metrics**:
+   - % users without email
+   - Notification delivery rates
+   - User engagement
