fix: workspace resolution via ArcGIS listLayer + seed UATs from uat.json

- resolveWorkspace: use listLayer() instead of listLayerByWhere() with
  hardcoded field names. Auto-discovers admin field (ADMIN_UNIT_ID/SIRUTA)
  from ArcGIS layer metadata via buildWhere().
- resolveWorkspace: persist WORKSPACE_ID to DB on first resolution for
  fast subsequent lookups.
- UATs POST: seed from uat.json (correct SIRUTA codes) instead of eTerra
  nomenclature API (nomenPk != SIRUTA, county nomenPk != WORKSPACE_ID).
- Remove eTerra nomenclature dependency from UATs endpoint.
- Fix activeJobs Set iteration error on container restart.
- Remove unused enrichedUatsFetched ref.
