docs(PhotoDialog): improve component documentation and error handling

- Add comprehensive JSDoc documentation for component features and capabilities - Fix line wrapping in file-level documentation header - Improve error message formatting for better readability - Remove unused PhotoResult interface - Maintain consistent documentation style with project standards The documentation improvements help developers better understand the component's cross-platform photo handling capabilities and error management approach.

+# Camera Implementation Documentation
+
+## Overview
+
+This document describes how camera functionality is implemented across the TimeSafari application. The application uses cameras for two main purposes:
+
+1. QR Code scanning
+2. Photo capture
+
+## Components
+
+### QRScannerDialog.vue
+
+Primary component for QR code scanning in web browsers.
+
+**Key Features:**
+
+- Uses `qrcode-stream` for web-based QR scanning
+- Supports both front and back cameras
+- Provides real-time camera status feedback
+- Implements error handling with user-friendly messages
+- Includes camera switching functionality
+
+**Camera Access Flow:**
+
+1. Checks for camera API availability
+2. Enumerates available video devices
+3. Requests camera permissions
+4. Initializes camera stream with preferred settings
+5. Handles various error conditions with specific messages
+
+### PhotoDialog.vue
+
+Component for photo capture and selection.
+
+**Key Features:**
+
+- Cross-platform photo capture interface
+- Image cropping capabilities
+- File selection fallback
+- Unified interface for different platforms
+
+## Services
+
+### QRScanner Services
+
+#### WebDialogQRScanner
+
+Web-based implementation of QR scanning.
+
+**Key Methods:**
+
+- `checkPermissions()`: Verifies camera permission status
+- `requestPermissions()`: Requests camera access
+- `isSupported()`: Checks for camera API support
+- Handles various error conditions with specific messages
+
+#### CapacitorQRScanner
+
+Native implementation using Capacitor's MLKit.
+
+**Key Features:**
+
+- Uses `@capacitor-mlkit/barcode-scanning`
+- Supports both front and back cameras
+- Implements permission management
+- Provides continuous scanning capability
+
+### Platform Services
+
+#### WebPlatformService
+
+Web-specific implementation of platform features.
+
+**Camera Capabilities:**
+
+- Uses HTML5 file input with capture attribute
+- Falls back to file selection if camera unavailable
+- Processes captured images for consistent format
+
+#### CapacitorPlatformService
+
+Native implementation using Capacitor.
+
+**Camera Features:**
+
+- Uses `Camera.getPhoto()` for native camera access
+- Supports image editing
+- Configures high-quality image capture
+- Handles base64 image processing
+
+#### ElectronPlatformService
+
+Desktop implementation (currently unimplemented).
+
+**Status:**
+
+- Camera functionality not yet implemented
+- Planned to use Electron's media APIs
+
+## Platform-Specific Considerations
+
+### iOS
+
+- Requires `NSCameraUsageDescription` in Info.plist
+- Supports both front and back cameras
+- Implements proper permission handling
+
+### Android
+
+- Requires camera permissions in manifest
+- Supports both front and back cameras
+- Handles permission requests through Capacitor
+
+### Web
+
+- Requires HTTPS for camera access
+- Implements fallback mechanisms
+- Handles browser compatibility issues
+
+## Error Handling
+
+### Common Error Scenarios
+
+1. No camera found
+2. Permission denied
+3. Camera in use by another application
+4. HTTPS required
+5. Browser compatibility issues
+
+### Error Response
+
+- User-friendly error messages
+- Troubleshooting tips
+- Clear instructions for resolution
+- Platform-specific guidance
+
+## Security Considerations
+
+### Permission Management
+
+- Explicit permission requests
+- Permission state tracking
+- Graceful handling of denied permissions
+
+### Data Handling
+
+- Secure image processing
+- Proper cleanup of camera resources
+- No persistent storage of camera data
+
+## Best Practices
+
+### Camera Access
+
+1. Always check for camera availability
+2. Request permissions explicitly
+3. Handle all error conditions
+4. Provide clear user feedback
+5. Implement proper cleanup
+
+### Performance
+
+1. Optimize camera resolution
+2. Implement proper resource cleanup
+3. Handle camera switching efficiently
+4. Manage memory usage
+
+### User Experience
+
+1. Clear status indicators
+2. Intuitive camera controls
+3. Helpful error messages
+4. Smooth camera switching
+5. Responsive UI feedback
+
+## Future Improvements
+
+### Planned Enhancements
+
+1. Implement Electron camera support
+2. Add advanced camera features
+3. Improve error handling
+4. Enhance user feedback
+5. Optimize performance
+
+### Known Issues
+
+1. Electron camera implementation pending
+2. Some browser compatibility limitations
+3. Platform-specific quirks to address
+
+## Dependencies
+
+### Key Packages
+
+- `@capacitor-mlkit/barcode-scanning`
+- `qrcode-stream`
+- `vue-picture-cropper`
+- Platform-specific camera APIs
+
+## Testing
+
+### Test Scenarios
+
+1. Permission handling
+2. Camera switching
+3. Error conditions
+4. Platform compatibility
+5. Performance metrics
+
+### Test Environment
+
+- Multiple browsers
+- iOS and Android devices
+- Desktop platforms
+- Various network conditions
