feat(audit): Cookie-Compliance-Audit (3-Quellen-Vergleich) + Vendor-Dedup + Block-Parser

ZENTRALER USP: cookie_compliance_audit.py vergleicht 3 Quellen
* DEKLARIERT in Cookie-Richtlinie (parse_cookie_table + parse_flat)
* TATSAECHLICH im Browser geladen (banner_result.phases.after_accept)
* LIBRARY-Metadaten (cookie_library lookup)

Liefert 3 Listen mit Compliance-Verdict:
* compliant (deklariert UND geladen) — gruener Block
* undeclared_in_browser (geladen NICHT deklariert) — ROTER HIGH-Block
  → Art. 13(1)(c) DSGVO + § 25 TDDDG Verstoss
* declared_not_loaded (deklariert NICHT geladen) — gelber Hinweis
  → Tabelle moeglicherweise veraltet

parse_cookie_table erweitert um Block-Format (5 Zeilen pro Cookie wie
beim User-Copy aus VW). Findet 35+ Cookies aus Copy-Paste statt 0.

vendor_normalizer.py: 50+ Aliases (Google-Familie, Adobe-Familie,
Trade Desk, AdForm, ...) + Garbage-Filter (URLs, leere Strings,
'click to select', 'Mehrere OEMs'). Mergt cookies-Listen beim Dedup.

_guess_vendor erweitert: Adobe-Familie (s_ecid/AMCV/demdex/mbox/...),
Trade Desk (TDID/TDCPM/TTDOptOut), AdForm (uid/cid/otsid),
Salesforce LiveAgent, etracker, Akamai, EDAA.

audit_quality_checks: vendor-thin-Threshold jetzt dynamisch nach
Cookie-Doc-Wörter (3k→10 / 6k→20 / 10k→30 / 15k+→40).

VW-Test-Fixture: tests/fixtures/cookie_gt/vw_cookie_richtlinie.txt
(36-Cookie-Sample fuer Regression-Tests).
