feat(consent+report): P56-P67 Mercedes-Audit-Cycle (Anti-Audit, Phase G Vendors, Cookie-Behavior-Validator + 5 Mail-Polish-Items) [migration-approved]

P56 Anti-Auditing-Detection als constructive Compliance-Finding (Audit-API- Empfehlung statt Anklage, weil Mercedes berechtigt Bots blockiert) P57 Phase G vendor_details Union mit cmp_vendors -> 42 Anbieter sichtbar P58 Anti-Audit-Detection robuster (Script-Domain-Check + Settings-spezifisch) P59 Cookie-Behavior-Validator (4 Layer, 3-Tier-Severity: MEDIUM=Kategorie- Mismatch / HIGH=Zweck-Mismatch / CRITICAL=beide=Vorsatz-Indiz) + Open Cookie Database (CC0) als Library-Seed (2264 Cookies) P59b Cookie-Behavior in Banner-Check verdrahtet + Mail-Block (BUGFIX: SessionLocal selbst oeffnen, db war im Background-Task nicht im Scope) Mail-Polish nach Mercedes-Review: P63 Banner-Footer-Links auch im wb7-link/role=link erkennen (Shadow-DOM- Walker label-based statt nur <a href>) P64 Re-Access-Severity: MEDIUM statt HIGH, wenn Footer "Einstellungen" oder Mercedes-typisch existiert; OEM-Footer-Detection (wb7-footer) P65 Text-Truncation: Word-Boundary statt Zeichen-Cut (kein "einfa"-Bruch mehr in Sofortmassnahmen) P66 GF-Aktionen: Service-Zweck vs Cookie-Zweck explizit erklaert (haeufige Verwechslung Marketing/GF: "Akamai-Beschreibung" != Cookie- Zweck pro DSK-OH 2024) P67 Stirring-Finding mit "Verlust-Framing"-Erklaerung + Alt-vs-Neutral- Beispiel, statt nur EDPB-Fachbegriff Compliance-Advisor FAQ (admin agent-core/soul): + CNIL/EDPB Top-Bussgelder (Google 100M, Meta 60M, Amazon 35M) + Deutsche Praezedenz (LG Muenchen Google Fonts, EuGH Planet49, BGH I ZR 7/16) + 4 Risiko-Pfade (Bussgeld/Abmahnung/Sammelklage/NOYB) + Berechnungs-Methodik Document-Generator Templates: AGB-DE (142), Impressum (140), Widerrufs- formular-Anlage (143), DSR-Process-Dedup (139), Cookie-Library (144). Architektur: doc_action_mappings.py + banner_dom_walkers.py + cookie_behavior_validator.py + vendor_detail_extractor.py rausgezogen, um die 500-LOC-Caps in agent_doc_check_report.py und banner_text_checker.py einzuhalten.
