KI-Feature 4.5.14: Feld-Diff für geänderte Stunden im AiAssistDialog

Statt Vorschläge nur pauschal als "Neu"/"Geändert" zu markieren, zeigt der Dialog jetzt je geänderter Stunde, was sich konkret unterscheidet (Thema, Datum, Beginn, Stundennummer, Hausaufgabe/Reflexion, Verlaufsplan) — AiPlanningService.DescribeChanges vergleicht bestehende Lesson und KI-Vorschlag feldweise und listet nur echte Unterschiede auf. Granulare Übernahme einzelner Phasen und Schutz vor Überschreiben eigener zwischenzeitlicher Änderungen als 4.5.19 zurückgestellt (größerer Umbau).
