CallReassignCloserPayload

Payload returned from callReassignCloser (AUR-1053). oldEventOrphaned is true when the old Nylas event failed to delete — the call row is still correctly updated but the old closer’s calendar may show a phantom event until async reconciliation cleans it up. attributionOnly is true when the call had already happened (AUR-2029) and only the closer credit moved — no calendar event was created or deleted.
