Zentrale Exception-Behandlung (Dispatcher.UIThread.UnhandledException, AppDomain, TaskScheduler) verhindert Abstürze und protokolliert Fehler über AppLogger in eine rotierende Log-Datei im App-Datenverzeichnis. Toast-Benachrichtigungen zeigen Erfolg/Fehler global an. Alle Dialoge mit Formularfeldern zeigen Validierungsmeldungen jetzt direkt am betroffenen Feld statt in einem Sammel-Label.
