Refactor repeater status screen and settings screen; add GPS toggle

- Updated _RepeaterStatusScreenState to load status after the first frame to avoid mid-build notifyListeners() calls.
- Removed unused _statusRequestedAt variable and adjusted _clockText() to use repeaterClockAtLogin for time display.
- Enhanced _SettingsScreenState with a GPS toggle switch that updates custom variables for GPS settings.
- Cleaned up RepeaterCommandService by removing redundant pending command checks and adjusted command ID generation.
- Removed jni plugin from generated_plugins.cmake for both Linux and Windows platforms.
