- Notenschlüssel-Editor im ExamDialog: Stufen (Note/Prozentgrenze) bearbeitbar, Vorbelegung passend zum GradingSystem der Gruppe, Live-Anzeige der absoluten Punktegrenze je Stufe, Validierung (lückenlos, keine Dopplungen) über GradingService.ValidateGradingKey. - Neues Modell GradingKeyTemplate + Repository: Notenschlüssel als Vorlage speichern/anwenden, direkt aus dem ExamDialog heraus. - Einstellungen: Fächer / Kompetenzen / Notenschlüssel-Vorlagen sind jetzt eigene Tabs statt einer gemeinsam wachsenden Liste. Vorlagen zeigen nur noch eine kompakte Zeile; die Stufen-Bearbeitung läuft über ein Popup-Fenster (GradingKeyTemplateDialog). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
