feat: Rechtliche-Texte-Module auf 100% — Dead Code, RAG-Fallback, Fehler-UI

Paket A:
- einwilligungen/page.tsx: mockRecords (80 Zeilen toter Code) entfernt
- consent/page.tsx: RAG-Suggest-Button im Create-Dialog (+handleRagSuggest)
- workflow/page.tsx: uploadError State + rotes Fehler-Banner statt alert()

Paket B:
- cookie-banner/page.tsx: mockCategories → DEFAULT_COOKIE_CATEGORIES (Bug-Fix)
  DB-Kategorien haben jetzt immer Vorrang — kein Mock-Überschreiben mehr
- test_einwilligungen_routes.py: +4 TestCookieBannerEmbedCode-Tests (36 gesamt)

Paket C:
- searchTemplates.ts: neue Hilfsdatei mit zwei-stufiger Suche
  1. KLAUSUR_SERVICE (5s Timeout), 2. RAG-Fallback via ai-compliance-sdk
- document-generator/page.tsx: ServiceMode State + UI-Badges (rag-only/offline)
- searchTemplates.test.ts: 3 Vitest-Tests (KLAUSUR ok / RAG-Fallback / offline)

flow-data.ts: alle 5 Rechtliche-Texte-Module auf completion: 100
