Changing the day of a repeating class now updates the session's finish time along with its start time.
- A moved session now runs for its full class length on the new day, instead of keeping the finish time from the old day.
- Appointment times that overlap the moved class are now correctly marked as unavailable for that instructor, so the same instructor can no longer be double-booked.
- The end date of the repeating series is unchanged when you move the day.
