fix(mobile): use @config-plugins/react-native-webrtc, link EAS project

- replace bogus @livekit/* plugin entries with @config-plugins/react-native-webrtc@^10 (real Expo config plugin; LiveKit packages do not ship app.plugin.js)
- eas init linked project @bygalax/netralax (id 255e2fde-...)
- app.json picked up Expo defaults (Android permissions, owner)
