feat: Analyse-Module auf 100% — Backend-Wiring, Proxy-Route, DELETE-Endpoints

7 Analyse-Module (Requirements, Controls, Evidence, Risk Matrix, AI Act,
Audit Checklist, Audit Report) von ~35% auf 100% gebracht:

- Catch-all Proxy-Route /api/sdk/v1/compliance/[[...path]] erstellt
- DELETE-Endpoints fuer Risks und Evidence im Backend hinzugefuegt
- Alle 7 Frontend-Seiten ans Backend gewired (Fetch, PUT, POST, DELETE)
- Mock-Daten durch Backend-Daten ersetzt, Templates als Fallback
- Loading-Skeletons und Error-Banner hinzugefuegt
- AI Act: Add-System-Form + assess-risk API-Integration
- Audit Report: API-Pfade von /api/admin/ auf /api/sdk/v1/compliance/ korrigiert
