feat: game info display, session car/track metadata

- Add GameInfo type + getGameInfo API call.
- Telemetry store polls /api/game-info every ~2s.
- Dashboard shows car @ track in Sim Connection section when receiving.
- SessionDetailView shows car_name and track_name in session info.
- Add car_name/track_name to UseCaseSession type.
