Subject: [PATCH] Fix errore Docker build quando secrets non configurati
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Aggiunto step 'Prepare image name' per gestire nome immagine dinamico
- Se secrets configurati: usa username/ha-voltronic-mqtt
- Se secrets mancanti: usa local/ha-voltronic-mqtt (build locale)
- Corretto flag SHOULD_PUSH basato su presenza secrets
- Risolto errore 'invalid tag' quando DOCKER_USERNAME è vuoto

Ora il workflow esegue build anche senza secrets configurati
