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

- uploadingPhoto
- photoUploadSuccess
- photoUploadFailed
- cameraError
- uploadError
- serverError
- retake
