Sitzungen (3.3): aus Stunde erzeugen, löschen, Kalenderüberblick; Doppelstunden-Bugfix Serienerzeugung
Kapitel 3.3: neuer Button erzeugt eine Mitarbeitssitzung aus einer geplanten Stunde (Datum/Thema, dupl.-sicher über Lesson.LessonId), Sitzungen lassen sich jetzt mit Rückfrage bei vorhandenen Bewertungen löschen, und der Dashboard-Kalender zeigt Sitzungen als dritten Termintyp neben Stunden/ Klausuren. Das Bearbeiten von Sitzungen war bereits vorhanden (undokumentiert aus früherer Ad-hoc-Arbeit) und wird hier nur nachgezogen. Bugfix: "Serie erzeugen" legte für Doppelstunden zwei Lessons mit gleichem Datum an statt einer, da jede Stundenplan-Periode einzeln behandelt wurde. Folgeperioden werden jetzt der Lesson der ersten Periode zugerechnet. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
