- Aggiunto check all'avvio per verificare esistenza inverter.conf e mqtt.json
- Se mancanti, crea file di default automaticamente
- Risolve problema volume mount che sovrascrive file copiati in build
- Config default con valori standard funzionanti
- ENV variables sovrascrivono comunque i default tramite update_mqtt_config()

Ora il container parte anche con directory ./config vuota
