Update Calendar Event
Partially updates a Task or Appointment. Only non-empty fields in the request body are applied; omitted fields keep their current values.
Notes:
- calendarId must be the composite string returned by POST /v2.0/calendar (e.g. ‘12345-task’ or ‘12345-appointment’). Invalid format returns 400.
- When startAt or endAt is supplied, it must be later than the current server time.
