Mosquitto: - Change restart: always (was unless-stopped) to survive daemon restarts - Add healthcheck (pub/sub ping) for depends_on conditions - All downstream services use condition: service_healthy Party-lock: - Add MQTT connection retry loop (was crashing on DNS race after restart) Zigbee2mqtt: - Add entrypoint wrapper that auto-applies BLZ bridge patch at startup - Bridge patch no longer needs manual 'just z2m-patch-bridge' after image pulls Mopidy: - Add python3-gi + python3-gi-cairo via apt (fixes 'No module named gi') - Set PYTHONPATH to expose system gi module to Python 3.12
