- Neue-Stunde-Dialog: Datum wird beim Anlegen anhand des Stundenplans
und der letzten Stunde der Einheit vorbelegt statt auf "heute"
(behebt eine falsch erkannte Doppelstunde, wenn "heute" nicht auf
den passenden Wochentag fiel).
- Zeiterfassung: Button "Unterrichtszeit heute übernehmen" schlägt
Start/Ende aus dem heutigen Stundenplan inkl. Puffer davor/danach vor.
- Dashboard: neue Kachel "Ungeplante Stunden" erinnert an Stunden ohne
Thema für heute/morgen, mit Opt-out je Gruppe ("Benötigt
Unterrichtsplanung"), Doppelstunden-Erkennung (keine doppelte Meldung
für die zweite Periode) und Berücksichtigung von Stundenausfall.
