feat(banner): Consent-Historie/Widerruf live erkennen (Borlabs-Stil, #62)

consent_history.detect_consent_history: erkennt CMP-Anbieter (Borlabs/
Usercentrics/OneTrust/Cookiebot/…) aus Storage+Cookies, versionierten Consent
(historie-fähig) + dauerhaftes Widerruf-/Einstellungs-Widget. consent_scanner
ruft es in Phase A; scan_matrix_summary surft summary.consent_history;
browser_cross_finding: positiver Befund wenn vorhanden, sonst Best-Practice-LOW
(„Nutzer sehen, wann sie welcher Version zugestimmt haben"); BrowserBehaviorView
zeigt es im Engine-Detail. Tests: 7 (classify/versioned) + 2 Cross-Finding.
