Issue #1: CloudScreen Zurück-Button — onZurueck Callback statt Navigator.pop() - CloudScreen erhält VoidCallback? onZurueck Parameter - Bei onZurueck != null → Callback (Tab-Wechsel in home_screen) - Fallback: Navigator.pop(context) für Standalone-Nutzung Issue #5: Token wird nur bei HTTP 401 gelöscht - _tokenOnlinePruefen(): nur statusCode == 401 → false - 5xx, andere Fehler, Netzwerkfehler → true (Token behalten) - Verhindert Ausloggen bei temporären Server-Problemen Issue #4: Android 13+ Berechtigungen beim App-Start - main.dart: frageSpeicherZugriff() + POST_NOTIFICATIONS nach Auth-Init - musik_scanner.dart: Permission-Check vor externen Ordnern in _sammleMusikPfade() Build: ⏭️ (no APK)
