fix: Amélioration de la gestion du Service Worker

- Réduction du timeout des updates de 10s à 5s
- Délai de 10s avant de démarrer l'intervalle de scan
- Logs améliorés pour diagnostiquer les blocages
- Cache Vite nettoyé pour éviter les erreurs TypeScript
- Meilleure gestion des erreurs dans l'intervalle de scan
- Service Worker plus robuste et moins bloquant
