feat: implement location selection interface with EXIF, GPS, and map picker

- Created LocationSelector component with three location input methods:
  * Auto-populate from photo EXIF data
  * Device GPS location capture with accuracy indicator
  * Interactive Leaflet map picker with draggable marker
- Added Ireland coordinate validation (lat: 51.4-55.4, lng: -10.5--5.5)
- Created coordinate utility functions for validation and formatting
- Added LocationSelectorDemo page for testing at /demo/location-selector
- Displays selected location with coordinates, source, and accuracy
- Provides clear error messages for validation failures
- Satisfies requirements 1.1, 1.2, 1.3, 8.2

+## LocationSelector
+
+An interactive location selection component that supports multiple input methods: EXIF data from photos, device GPS, and manual map selection.
+
+### Features
+
+- **Auto-population from EXIF**: Automatically extracts and uses GPS coordinates from uploaded photos
+- **Device GPS capture**: One-click button to use device's current location
+- **Interactive map picker**: Leaflet-based map for manual location selection with draggable marker
+- **Ireland validation**: Validates that selected coordinates are within Ireland's boundaries
+- **Accuracy indicator**: Displays GPS accuracy with quality labels (Excellent, Good, Fair, Poor)
+- **Visual feedback**: Clear indicators showing selected location, source, and coordinates
+- **Error handling**: User-friendly error messages for validation failures and GPS errors
+
+### Usage
+
+```typescript
+import { LocationSelector } from '@/components/report';
+import { PhotoMetadata } from '@/components/report';
+import { Coordinates, LocationSource } from '@/types';
+
+function ReportForm() {
+  const [photos, setPhotos] = useState<PhotoMetadata[]>([]);
+  
+  const handleLocationChange = (
+    location: Coordinates,
+    source: LocationSource,
+    accuracy?: number
+  ) => {
+    console.log('Location:', location);
+    console.log('Source:', source); // 'exif', 'gps', or 'manual'
+    console.log('Accuracy:', accuracy); // GPS accuracy in meters (if available)
+  };
+
+  return (
+    <LocationSelector
+      photos={photos}
+      onLocationChange={handleLocationChange}
+      initialLocation={undefined} // Optional: pre-populate location
+    />
+  );
+}
+```
+
+### Props
+
+- `photos`: Array of PhotoMetadata objects (from PhotoUpload component)
+- `onLocationChange`: Callback function called when location is selected or changed
+- `initialLocation`: Optional initial coordinates to pre-populate the selector
+
+### Location Sources
+
+- **exif**: Location extracted from photo EXIF metadata
+- **gps**: Location obtained from device GPS
+- **manual**: Location selected manually on the map
+
+### Ireland Coordinate Bounds
+
+The component validates coordinates against Ireland's geographical boundaries:
+- Latitude: 51.4° to 55.4°
+- Longitude: -10.5° to -5.5°
+
+### Requirements Satisfied
+
+- **1.1**: Captures geographical coordinates with accuracy within 10 meters (via GPS)
+- **1.2**: Auto-populates location from EXIF data when available
+- **1.3**: Prompts for location via device GPS or manual map selection when EXIF is unavailable
+- **8.2**: Accesses device GPS capabilities to auto-populate report location coordinates
