fix(snapshot): Cookie-Dedup + schneller Impressum-Tab + Tabellen-Zahl

- Cookies werden je Vendor nach Name dedupliziert (Consent-Phasen-Dubletten;
  BMW 2196 → ~772) — in cookie-check + get_snapshot, behebt aufgeblähte
  Kachel-/Finding-Zahlen.
- Impressum-Snapshot-Check überspringt den ~40s-LLM-Schritt (context skip_llm)
  → Tab lädt sofort statt leer zu bleiben.
- Vendor-Tabelle zeigt nur die Cookie-Zahl (kein 'Cookies'-Wort je Zeile).
