 * in GisFeature with:
 *   - geometry = null
 *   - geometrySource = "NO_GEOMETRY"
 *   - objectId = negative immovablePk (to avoid collisions with real OBJECTIDs)
 *

 *   1. Fetch full immovable list from eTerra for the UAT (paginated)
 *   2. Load all existing cadastralRefs from DB for TERENURI_ACTIVE + siruta
 *   3. Immovables whose cadastralRef is NOT in DB → candidates
 *   4. Store each candidate as a GisFeature with geometry=null
