feat(cookie): Pro-Cookie-Library-Abgleich (2287er OCD + 35er rich) + Panel

- analyze_cookies gleicht Cookies gegen BEIDE Libraries ab: compliance.cookie_library
  (2287, OCD/CC0 — Kategorie/Retention) + 35er rich-DB (technical_necessity/reid/
  schrems/eu_alternative). 5 Befund-Typen: tracker_as_necessary, missing_purpose,
  excessive_lifetime (Art.5), third_country (Art.44), eu_alternative (kommerziell).
- Endpoint GET /snapshots/{id}/cookie-check (load_big_library batch + analyze).
- Frontend CookieLibraryPanel im Snapshot-Detail.
- Fix CookieResultView: Zweck nicht mehr auf 60 Zeichen gekuerzt; Rolle 'unknown'
  als Strich statt 'Unbekannt'.

Tests: 7 backend + frontend vitest gruen.
