Notenverwaltung (Kapitel 2) und Mitarbeits-Assistent

Notenübersicht der Gruppe (Matrix, Gesamt-Spalte, Sortierung, Halbjahresfilter), Einzelnoten-Pflege samt Sammelerfassung, Gewichtungsschema mit Voreinstellung je Gruppentyp, Zeugnisnoten-Berechnung mit Übersteuern/Festschreiben/Export und Notenentwicklung im Schülerdetail. Dazu Anwesenheits-/Hausaufgaben-Tracking je Mitarbeit-Sitzung, ein neuer Mitarbeits-Assistent (Zeitleiste mit Abschnitten, automatischer Notenvorschlag, Zusammenzug zur Halbjahresnote) und eine Dashboard-Kachel für offene Entschuldigungen. Außerdem: verbliebene englische Begriffe in Auswahlfeldern und Buttons auf Deutsch umgestellt.
