Notenschlüssel-Editor (1.3) und Einstellungen in Tabs strukturiert

Browse Source 
- 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).
