feat: Auto-discovery parallelo con timeout e stile originale

- Aggiunto timeout 15s al parallel discovery per evitare blocchi
- mqtt-init-parallel.sh in stile originale semplice
- Per ogni inverter scoperto: registra topic discovery (voltronic_inv1_*, inv2_*, ...)
- Discovery topics ogni 10 minuti invece di 5
- Fallback automatico a single-mode se timeout o count=0
- Mantiene la semplicità dello script originale

Il parallel discovery testa QPGS0-9 per trovare inverter configurati in parallelo.
Se timeout o nessun inverter trovato, usa modalità standard.
