feat: filter no-geom by IE status (hasLandbook), add checkIfIsIE + CF PDF APIs

QUALITY GATE TIGHTENED:
No-geometry import now requires hasLandbook=1 (imobil electronic).
This filters out immovables without carte funciara — they have no
CF data, no owners, no parcel details to extract. For Cosbuc this
reduces useful no-geom from ~1916 to ~468 (only IEs with real data).

Three-tier quality gate:
1. Active (status=1)
2. Has landbook (hasLandbook=1) — is electronic immovable  [NEW]
3. Has identification (cadRef/paperLbNo/paperCadNo) OR area

CLEANUP also updated: DB cleanup now removes stale no-geom records
that don't pass the tightened gate (existing non-IE records will be
cleaned on next import run).

NEW API METHODS (eterra-client):
- checkIfIsIE(adminUnitId, paperCadNo, topNo, paperCfNo) → boolean
  Calls /api/immovable/checkIfIsIE — verifies IE status per-parcel
  Available for future per-item verification if needed
- getCfExtractUrl(immovablePk, workspaceId) → string
  Returns URL for /api/cf/landbook/copycf/get/{pk}/{ws}/0/true
  Downloads the CF extract as PDF blob (future enrichment)

UI updated: 'Filtrate' label now says 'fara CF/inactive/fara date'
to reflect the new hasLandbook filter.
