fix: Pulizia topic legacy e discovery retention

- Rimosso vecchio topic homeassistant/sensor/voltronic/config all'avvio
- Aggiunto flag -r (retain) a tutti i discovery topics
- MQTT init eseguito immediatamente all'avvio + ogni 5 minuti
- Aggiunto unique_id e device info a tutti i sensori per HA
- mqtt-subscriber ora ascolta su 3 topic:
  - homeassistant/sensor/voltronic/command (legacy)
  - homeassistant/sensor/voltronic_inv1_raw_cmd/command
  - homeassistant/sensor/voltronic_inv2_raw_cmd/command
- Subscriber con output verbose e timestamp
- Discovery topics ora persistono dopo restart broker MQTT

Timing verificato:
- Init all'avvio: immediato
- Re-init periodico: ogni 5 minuti (300s)
- Data push: ogni 30 secondi
