feat: Consent Migration Phasen 3-6 — Cookie Banner, Deadlines, Public DSR, Integrations

Phase 3 (Cookie Banner): Backend + Frontend existierten bereits —
keine Aenderungen noetig.

Phase 4 (Deadlines): DeadlineTab mit Fristen-Timeline (30 Tage,
4 Erinnerungen, Auto-Sperrung). Backend-Cron in Production via Core.

Phase 5 (Public DSR): PublicFormConfig im DSR Settings-Tab —
konfigurierbare Anfragetypen, Identitaetspflicht, Embed-Code.

Phase 6 (Integrations): IntegrationStubs fuer Matrix, Jitsi, OAuth,
2FA, Notifications — vorbereitet fuer Core-Service-Anbindung.

Consent Management: 2 neue Tabs (Fristen, Integrationen).
DSR: Settings-Tab mit Public Form statt Platzhalter.
