Fix: Configurazione workflow Gitea per registry insecure

- Aggiunta configurazione buildx per registry con http/insecure
- Sostituito login-action con autenticazione manuale tramite config.json
- Aggiornate versioni actions (buildx v3, build-push v6)
- Aggiunto provenance: false e outputs con registry.insecure=true
