The Meshtastic MQTT bridge was using client.loop(timeout=1.0) in a
blocking while loop. When the broker dropped the connection (common
after ~30s of idle in Docker), the client silently stopped receiving
messages with no auto-reconnect.
Switch to client.loop_start() which runs the MQTT network loop in a
background thread with built-in automatic reconnection. Also:
- Add on_disconnect callback for visibility into disconnection events
- Set reconnect_delay_set(1, 30) for fast exponential-backoff reconnect
- Lower keepalive from 60s to 30s to stay within Docker network timeouts
