Baud rate is now a first-class device field, passed through the full stack: Device model → API schemas → routes → ProcessorManager → AdalightClient. The frontend shows a baud rate dropdown (115200–2M) for Adalight devices in both Add Device and Settings modals, with a live "Max FPS ≈ N" hint computed from LED count and baud rate.
