feat(audit): P107 Branchen-Benchmark-Cockpit fuer Big-4-Demos

benchmark_extractor.py — extract_kpis() liefert 18 KPIs pro Snapshot:
* vendors_total, vendors_us, vendors_non_eu (mit % je Vendor-Land)
* source_breakdown (llm/library/flat_pattern/table_paste/html_table_dom)
* max/avg cookies_per_vendor (Konzentrations-Mass)
* cookies_in_browser, cookies_detailed_count, cookie_doc_chars
* banner_detected, banner_provider, banner_violations
* compliance_score, data_quality_pct (wie viele unserer Datenquellen
  haben Inhalt)
* saving_low/high_eur (Heuristik: (vendors - 10) × 1k-5k)

anonymize_kpis() ersetzt site_label durch 'OEM 1/2/3' (Industry-Prefix
Map: automotive→OEM, banking→Bank, chemistry→Chem, luftfahrt→Airline).

GET /api/compliance/agent/admin/benchmark?industry=automotive&sites=
VW,BMW,Mercedes&anonymized=true — liefert kpis + summary
(n_sites, avg_vendors, total_saving_high).

Admin-Page /sdk/benchmark:
* Filter-Leiste: Industry-Dropdown, Sites-Input + 5 Preset-Gruppen
  (Automotive OEMs / Zulieferer, Chemie DAX, Luftfahrt, Banking DAX)
* Anonymize-Toggle prominent
* 5 Summary-KPI-Karten oben
* Vergleichstabelle 13 Spalten (Score, Vendors, US%, Drittland%,
  Cookies-Browser, Cookie-Doc-kB, Banner ✓/✗, Provider, Verstoesse,
  Saving €/Jahr, Daten-Qualitaet, Captured-Time)
* Red-/Amber-/Green-Indikatoren bei US%/Score/Drittland
* Big-4-Hinweis-Footer
