docs(profiles): match the job create response in openapi

The 202 body documented usage_units and a results array. The API returns
entity_count_reserved, event_id and, for sample jobs, entity_ids; results
only appears on GET /v2/profiles/jobs/{id}/. The SDK types already use
entityCountReserved and entityIds, so the spec was the one out of step.

The docs sample example indexes entity_ids with .get(), matching the
notebook and the TS example's ?? [].
