feat(cmp): Phase 3 — admin widerruf, email-linking, vendor display, TCF, E2E tests

Admin Modal:
- vendor_consents as green/red badges
- Consent withdraw button (DELETE /consent/{id}) with confirmation
- Email-linking inline input (POST /consent/link-email)

Cookie Banner Admin:
- TCF toggle reads tcf_enabled from site config (was hardcoded false)
- BannerSite interface extended with tcf_enabled

Document Generator:
- Backend Banner-Config auto-fetch when SDK state has no banner
- Maps vendors to CONSENT (analytics tools, marketing partners)

E2E Tests (cmp-phase3-dsr.spec.ts):
- Vendor-agnostic consent fields (20+ fields, upsert)
- DSR Art. 15 Auskunft (multi-device, email-link, export)
- DSR Art. 17 Löschung (erasure by email)
- Anonymous cookie banner user (export, withdraw)
- Customer lifecycle (consent → login → link → Art.15 → Art.17)
- Admin dashboard integration (list, stats)
