Returns a paginated list of field descriptors for the specified dataset. Each field includes its machine-readable name, human-readable label, parent section type and name, and entityName. Use the returned field name values in the fields array when querying data via "Get Data from Dataset (v2)". Use "List Datasets (v1.2)" to discover valid datasetName values. Pagination defaults to page 1 with 500 fields per page (maximum 1000). Out-of-range page numbers are clamped to the nearest valid page.

Note: Compared to "Get Fields from Dataset (v1)", this version returns RFC 7807 application/problem+json error responses and includes an X-Request-ID correlation header.
