Unterrichtsplanung: Einheiten, Verlaufsplan-Editor, Kürzel-Katalog (Kapitel 4.1/4.2)

Neuer Tab "Planung" in GroupDetailView ersetzt den Platzhalter: Einheiten anlegen/bearbeiten/ als Vorlage in andere Gruppe kopieren, Stunden je Einheit mit Verschieben (inkl. Nachrücken der Folgestunden). Stundeneditor als tabellarischer Verlaufsplan (Phase/Dauer/Tätigkeit/ Material/Kurzsymbol je Zeile, Uhrzeit aus optionalem Stundenbeginn abgeleitet) statt eines einzelnen Phase-Felds mit Methoden-/Materialien-Chips — Kurzsymbol als Freitext mit Vorschlägen aus neuem Kürzel-Katalog (Einstellungen) plus bisher verwendeten Werten. Schema-Migrationen v1-v3 überführen bestehende Daten verlustfrei. 4.2.5 bewusst offen gelassen (hängt an Stundenplan, Kapitel 4.3). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
