Searches the work locations of a single employer, identified by the path
parameter {employerId}. Returns a page of work locations matching the
supplied filters. Use the work-location metadata endpoint
(/v1/employers/work-locations/metadata/search) to discover
available field IDs and supported filter operators. There is no
single-work-location endpoint — read one by filtering on /workLocation/id.
(Work-location metadata is not employer-scoped; its endpoint is
/v1/employers/work-locations/metadata/search.)

Before using this endpoint

• Discover readable field IDs (including custom fields) via the
  work-location metadata search endpoint.
  Out-of-the-box field IDs are also listed as keys on the WorkLocation
  response schema for this search endpoint.
• Provide a numeric employerId in the path — use the employer search
  endpoint to look up employer IDs.
• There is no single-work-location endpoint — filter on /workLocation/id
  with operator equals to read one work location.
• Filterable field IDs: /workLocation/id, /workLocation/name,
  /workLocation/type, /workLocation/status, /workLocation/country. Any
  other fieldId in filters returns 400 Bad Request.

Pagination — cursor-based. next_cursor is null on the last page.
Search does not support sorting — order results client-side.

Testing notes

• Use the testing widget's Try It! option to test this endpoint.
• Open Examples and select Request Example to populate the request
  body. Replace the path employerId with a real employer ID from your
  company.
• IDs must be sent as JSON strings even when they look numeric.
