feat: Enhance HomeScreen with RX/TX indicators and long press functionality

- Added GestureDetector to RX/TX indicators for long press to open PacketLogScreen.
- Refactored RX/TX indicator code for better readability.
- Updated disconnect button to maintain functionality.

feat: Extend MeshCoreBleService with new login and message handling features

- Introduced new callbacks for device info, message waiting, login success, and login fail.
- Implemented handling for new message waiting and login success/fail pushes.
- Enhanced device info parsing to include additional fields such as firmware version, max contacts, and more.

fix: Correct MeshCoreConstants response codes

- Added new response codes for custom variables, advertisement path, and tuning parameters.
