feat: Enhance device configuration and location tracking features

- Refetch device info after updating settings in device_config_screen.dart.
- Update map_tab.dart to use singleton instance of LocationTrackingService and streamline location tracking callbacks.
- Modify ble_response_handler.dart to handle contact not found errors and improve error callback structure.
- Enhance location_tracking_service.dart with retry logic for GPS position acquisition and initial position setting without broadcasting.
- Update meshcore_ble_service.dart to track last contact for auto-recovery on errors.
- Improve tile_cache_service.dart error messages and streamline tile download logic.
- Add current GPS location insertion feature in direct_message_sheet.dart with permission checks.
- Update pubspec.lock and pubspec.yaml to include integration_test dependency.
- Add screenshot automation script for iOS and Android devices.
- Create integration test driver for screenshot capturing.
