- neues Paket mqttheartbeat: Publisher mit paho, topic signage/screen/<id>/heartbeat,
payload {screen_id, ts, status, server_connectivity}, auto-reconnect bei Ausfall
- MORZ_INFOBOARD_MQTT_BROKER leer (Standard) -> MQTT komplett uebersprungen
- app.emitHeartbeat() publiziert bei jedem Tick per MQTT wenn Broker konfiguriert,
loggt Fehler und laeuft weiter (kein Stop bei MQTT-Ausfall)
- mqtt.Close() bei context.Done()
- MQTTBroker-Default von tcp://127.0.0.1:1883 auf "" geaendert
- erste externe Dep: github.com/eclipse/paho.mqtt.golang v1.5.1
