A lighter status page. Returns the same per-item status entries as
GET /lang2fhir/batch/{job_id}, but without the job record or counts,
and the entries carry result_size rather than any result content. Use
each entry's item_id to fetch that item's result from
GET /lang2fhir/batch/{job_id}/results/{item_id}.

Entries are listed in a stable order that is not upload order and is
the same across pages. Match each entry to your own records by its id
(your correlation label) or item_id (from the upload response),
never by position.
