New Dataset Fields v1.2 Endpoint

We added the following public API endpoint for retrieving fields from a dataset:

• Get Fields from Dataset v1.2 (GET /api/v1_2/datasets/{datasetName}/fields)

This v1.2 endpoint returns standardized RFC 7807 error responses with structured error codes and supports X-Request-ID for request tracing. Existing integrations using the corresponding v1 endpoint do not need to migrate immediately.

Review the linked documentation for more information.
