fix: full patch - reconnect_delay, keepalive, clean_session, QoS1

Patches for paho-mqtt rc=7 at startup (MQTT_ERR_CONN_LOST):

1. reconnect_delay_set(1, 30) - auto-reconnect with backoff
2. keepalive=120 - prevents timeout during long OTP startup
3. subscribe(otp_topic) in on_connect - no race condition
4. time.sleep(0.05) - prevents TCP socket buffer overflow
5. clean_session=False - queued messages survive reconnect
6. qos=1 for discovery configs - PUBACK confirms delivery
