auto-claude: subtask-2-3 - Create PhotoCaptureDialog component for photo confirmation

Add PhotoCaptureDialog widget component that:
- Shows captured photo preview with proper constraints
- Displays confirmation message using delivery name
- Provides Cancel and Upload action buttons
- Uses theme-aware styling with colorScheme
- Handles image loading errors gracefully
- Includes proper i18n support (EN/FR)

Added localization keys:
- confirmPhoto
- uploadPhotoConfirmation (with name placeholder)
- uploadingPhoto
- photoUploadSuccess
- photoUploadFailed
- cameraError
- uploadError
- serverError
- retake
