fix(parcel-sync): resolve county names 100% from eTerra, zero hardcoding

LIMITE_UAT gives SIRUTA + WORKSPACE_ID for all 3186 UATs. For each of
the 42 unique workspaces, fetch 1 immovable via fetchImmovableListBy
AdminUnit — the response includes workspace.name = county name.
No static mappings, no nomenclature endpoints (they 404).

- * 3. For initial bootstrap: use a well-known UAT→county mapping to seed
