📄 Description

update_event only verified write access on the event's source calendar. CalendarEventUpdateForm accepts a new calendar_id which the model layer applies unconditionally, so a user with write access to their own calendar could move (inject) an event into any other user's calendar. Mirror the destination check create_event already performs.
