fix(parcel-sync): use verified WORKSPACE_ID → county mapping from eTerra

LIMITE_UAT provides SIRUTA + WORKSPACE_ID for all 3186 UATs across 42
workspaces. eTerra nomenclature APIs all return 404, and immovable list
returns empty for small communes. Use verified workspace→county mapping
derived from eTerra data (cross-referenced sample UATs + DB confirmations).
Logs unknown workspaces if eTerra ever adds new ones.

- * County refresh — populates GisUat.county from eTerra.
+ * County refresh — populates GisUat.county from eTerra LIMITE_UAT layer.
  *
  * Called with an already-authenticated EterraClient (fire-and-forget
  * after login), so there's no session expiry risk.
  *
- * Strategy (100% from eTerra, zero hardcoding):
+ * Strategy:
  * 1. Query LIMITE_UAT for all features (no geometry) →
  *    get ADMIN_UNIT_ID (SIRUTA) + WORKSPACE_ID per UAT
- * 2. Group by WORKSPACE_ID → 42 unique workspaces (= 42 counties)
- * 3. For each workspace, pick one SIRUTA and call
- *    fetchImmovableListByAdminUnit(workspaceId, siruta, page=0, size=1)
- *    → response includes workspace.name = county name
- * 4. Batch-update GisUat.county + workspacePk
+ * 2. Map WORKSPACE_ID → county name. eTerra uses fixed workspace IDs
+ *    for Romania's 42 counties — these are stable infrastructure identifiers
+ *    (Romania has had 41 counties + București since 1997).
+ * 3. Batch-update GisUat.county + workspacePk
+ *
+ * If a new workspace appears (eTerra adds one), it's logged for manual
+ * investigation. The mapping is verified against known UATs in each county.
