Subject: [PATCH] feat: Consent-Service Module nach Compliance migriert (DSR,
 E-Mail-Templates, Legal Docs, Banner)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

5-Phasen-Migration: Go consent-service Proxies durch native Python/FastAPI ersetzt.

Phase 1 — DSR (Betroffenenrechte): 6 Tabellen, 30 Endpoints, Frontend-API umgestellt
Phase 2 — E-Mail-Templates: 5 Tabellen, 20 Endpoints, neues Frontend, SDK_STEPS erweitert
Phase 3 — Legal Documents Extension: User Consents, Audit Log, Cookie-Kategorien
Phase 4 — Banner Consent: Device-Consents, Site-Configs, Kategorien, Vendors
Phase 5 — Cleanup: DSR-Proxy aus main.py entfernt, Frontend-URLs aktualisiert

148 neue Tests (50 + 47 + 26 + 25), alle bestanden.
