feat: modalità amichevole e fix URL remoti in dev (WSL2)

- Aggiunge modalità "Amichevole" in config: i set si vincono normalmente
  ma la partita non termina mai automaticamente (checkVittoriaPartita
  restituisce false), consentendo di giocare set illimitati
- Dev server ora espone su tutte le interfacce (vite --host)
- printServerInfo mostra Display + Controller per dispositivi remoti
- Su WSL2 getNetworkIPs() interroga PowerShell per ottenere gli IP
  Windows reali invece degli IP interni WSL (172.x)
