feat: Pädagogische Klassen-Aufgaben, Prioritäten/Checklisten, Dashboard-Schnellzugriffe

Neue Aufgabenart über bestehende Felder (WorkTask.Kind=Reminder + GroupId) statt Vererbung,
mit Priorität (TaskPriority) und optionaler Abhak-Liste (ChecklistItems, wahlweise Kurs-
Roster oder Freitext). Kurs-Dashboard zeigt jetzt eine "Anstehende Aufgaben"-Karte samt
direktem Anlege-Button; derselbe Anlege-Einstieg wurde auch ins Hauptdashboard und (als
Schnellüberblick samt fehlender Übersicht/Mitarbeit-Buttons) in die Gruppenliste gezogen.
