Fix UpsertMultiple: don't merge alternate key fields into request body

tpellissier · claude · tpellissier · commit cfc2056d23f9 · 2026-02-26T15:30:54.000-08:00
Alternate key values must only appear in @odata.id, not in the record
body. Including them in both causes Dataverse to return 400 Bad Request.
Confirmed via raw curl that removing the duplicate fields resolves it.
