feat: Sistema controllo accessi Focolari completo con test E2E

🎯 Funzionalità Implementate:
- Frontend React/TypeScript/Tailwind ottimizzato per tablet
- Backend mock FastAPI con API complete
- Hook RFID multi-pattern (US: ;? / IT: ò_)
- Flusso validatore → partecipante → conferma ingresso
- Carosello benvenuto multilingua (10 lingue, animazione smooth)
- Gestione sessione con invalidazione su server restart
- Pagina debug RFID accessibile da /debug

🧪 Test Implementati:
- 56 unit test (Vitest) - hook RFID, API, componenti
- 14 test E2E (Playwright) - flussi completi con browser reale
- Test sicurezza: verifica blocco backend per utenti non ammessi

📋 Comandi Disponibili:
- ./dev.sh install     → Setup dipendenze
- ./dev.sh dev         → Sviluppo (hot reload)
- ./dev.sh server      → Produzione locale
- ./dev.sh test        → Unit test
- ./dev.sh test:e2e    → Test E2E headless
- ./dev.sh test:e2e:headed → Test E2E con browser visibile
- ./dev.sh test:e2e:ui → Playwright UI per debug

📝 Documentazione:
- README.md con guida completa
- API_SPECIFICATION.md per backend reale
- TEST_CHECKLIST.md per test manuali
- Piani sviluppo in ai-prompts/

⏳ Stato: MVP completo, in attesa di feedback e richieste future
