- Add NotificationService for handling local notifications.
- Introduce StorageService for key-value storage using SharedPreferences.
- Create DeviceLocation model to represent geographic locations.
- Define LocationPermissionStatus enum for managing location permissions.
- Implement BackgroundGeofenceService for periodic geofence checks while clocked in.
- Develop GeofenceServiceImpl for geofence proximity verification using LocationService.
- Create GeofenceResult model to encapsulate geofence check results.
- Define GeofenceServiceInterface for geofence service abstraction.
- Implement GeofenceBloc to manage geofence verification and background tracking.
- Create events and states for GeofenceBloc to handle various geofence scenarios.
- Add GeofenceStatusBanner widget to display geofence verification status in the UI.
