frontend: Update-Detection überarbeitet - nur anzeigen wenn User aktiv ist
- Service Worker prüft im Hintergrund auf neue Versionen (jede 5 Minuten) - Update-Status wird in localStorage gespeichert - Benachrichtigung erscheint nur wenn: * User zur App zurückkommt (Page Visibility API) * Oder beim initialen Laden wenn Update verfügbar - "Später" Button zum Dismissieren, "Jetzt laden" für Reload - Keine Browser-Permission nötig - localStorage-Daten bleiben beim Reload erhalten - Pragmatisch: User sieht Updates nur wenn er arbeitet Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
