feat: In-App-Update (Download + Installer direkt öffnen)
"Jetzt aktualisieren"-Button im Update-Banner lädt die neue APK vom Server herunter (mit Fortschrittsbalken) und öffnet danach direkt den Android- Paketinstaller (open_filex + FileProvider). Kein Silent-Install (App ist nicht Geräteeigentümer/MDM) – User bestätigt die Installation weiterhin im System-Dialog, muss nur nicht mehr manuell ins Portal wechseln. REQUEST_INSTALL_PACKAGES-Permission + FileProvider-Konfiguration ergänzt. v0.1.7+8.
