feat: Legal Templates Service — eigene Vorlagen für Dokumentengenerator

Implementiert MIT-lizenzierte DSGVO-Templates (DSE, Impressum, AGB) in
der eigenen PostgreSQL-Datenbank statt KLAUSUR_SERVICE-Abhängigkeit.

- Migration 018: compliance_legal_templates Tabelle + 3 Seed-Templates
- Routes: GET/POST/PUT/DELETE /legal-templates + /status + /sources
- Registriert im bestehenden compliance catch-all Proxy (kein neuer Proxy)
- searchTemplates.ts: eigenes Backend als Primary, RAG bleibt Fallback
- ServiceMode-Banner: KLAUSUR_SERVICE-Referenz entfernt
- Tests: 25 Python + 3 Vitest — alle grün
