Stundenplan: Wochenraster, Wochennavigation, Ferien/Feiertage (Kapitel 4.3)

Neuer Stundenplan mit "Heute"-Standardansicht (Tagesliste unten angedockt, gruppenübergreifendes Wochenraster mit Fach/Klasse/Raum/Thema, Vor-/Zurück- Navigation zwischen Kalenderwochen) und separatem Bearbeiten-Raster für die wöchentliche Zuordnung. Badges für Ferien-/Klausur-Nähe und ausgegraute Ferientage direkt im Plan statt einer separaten Liste. Ferien-/Feiertage- Pflege (Bundesland, Schulferien) sitzt jetzt in den Einstellungen statt im Stundenplan selbst. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
