fix: Runde-2-Fixes – Monatsauswahl, CalDAV-Update, Lösch-Dialog, EXDATE

- Monatsansicht: selectedDate von currentDate getrennt, Klick verschiebt View nicht mehr - Selected-Day Styling: weißer Text auf Primary-Hintergrund statt nur Textfarbe - Kontextmenü: --bg-surface statt fehlendem --bg-card - CalDAV Update/Delete: parent Calendar-Objekt übergeben (behebt NoneType-Fehler) - HA-Kalender im Kalender-Selektor ergänzt - Browser-confirm() durch styled Modal-Dialog ersetzt mit Serie/Einzeln-Option - EXDATE-Support: einzelne Vorkommen wiederkehrender Termine löschen (lokal + CalDAV) - Fehlende i18n-Keys für Lösch-Dialog ergänzt (DE + EN)
