- Updated ConnectionProvider to track pending messages before sending to avoid race conditions. - Integrated ValidationService in DeviceConfigScreen for validating latitude, longitude, frequency, and TX power inputs. - Added bounds and zoom level validation in MapManagementScreen using ValidationService. - Refactored MapTab to utilize LocationTrackingService for location updates and removed deprecated location permission handling. - Replaced BackgroundLocationService with LocationTrackingService in SettingsScreen, improving location update management and error handling. - Enhanced SAR Update Sheet to validate coordinates, notes length, and location accuracy before sending SAR markers.
