Add localization support for various UI elements and messages

- Integrated localization for alert dialogs, snack bars, and button labels in PacketLogScreen and SettingsScreen.
- Updated location tracking service messages to use localized strings.
- Enhanced ContactTile and DirectMessageSheet with localized text for user interactions.
- Implemented localization in DrawingLayer and DrawingToolbar for map-related actions.
- Updated SAR Update Sheet to utilize localized strings for user prompts and actions.
- Ensured consistent use of localization across all relevant widgets and screens.
