Add in-game settings menu with web panel sync

Features:
- SettingsActivity accessible via Menu button (keycode 82)
- Configure server URL and mode (online/offline) in-game
- Test connection before saving settings
- Switch to offline mode with one tap
- Sync settings from web admin panel
- Real-time status messages with emoji indicators

Implementation:
- Created 13 SettingsActivity Smali files (main + inner classes)
- Created activity_settings.xml UI layout
- Added SettingsActivity to AndroidManifest.xml (portrait mode)
- Modified MainActivity.smali to handle Menu button press
- Integrated with existing ServerManager for Nimble SDK overrides
- Settings stored in SharedPreferences (rr3_server_config.xml)

APK:
- Built and signed: RR3-v14-Settings-Menu.apk (103 MB)
- Keystore: rr3-release.keystore (alias: rr3key)
- Ready for distribution

Related server changes:
- ServerSettingsController.cs with 3 API endpoints
