fix: resolve display stuck after disconnect and radio task deadlock

0 Fork 0

- Set disconnected flag on DisplayCommand::Reset to block stale radio
  status updates from re-rendering dashboard over splash screen
- Send StopRx to radio when USB DTR drops so radio stops generating
  packets after host disconnects
- Use try_send for unsolicited responses (RxPacket, error recovery,
  StopRx Ok) to prevent radio task deadlock on full response channel
- Fall back to LED-only event loop when display init fails instead of
  returning early and orphaning the LED
