OnSched 3.11.1 - restore calendar padding after override 0

API

• Padding events can return after 0: PUT /v3/appointment/{id} with a positive overridePadding recreates the separate Google or Outlook padding event when the appointment already has a main calendar event. Previously, setting padding to 0 cleared the padding event id, so a later increase never wrote a new padding event.
• Zero still removes a stored padding event: overridePadding: 0 deletes the padding event when its id is stored. The main appointment event is not replaced.
• Unaffected: Appointments that were never synced to an external calendar still do not get a padding event from a padding-only update.
