Paul Bailey cdd8c0fc08 fix: Improve Piper TTS error handling and user messaging ...

- Added proper error handling for missing voice models in preview endpoint
- Return 404 with helpful message when Piper models not found
- Added user-friendly alert in frontend when preview fails
- Added prominent warning in UI when Piper is selected about manual setup
- Check for empty audio before returning to prevent decode errors

Users now get clear feedback when Piper voice models are missing
instead of cryptic 'media could not be decoded' errors.
