feat: Vorbereitung-Module auf 100% — Compliance-Scope Backend, DELETE-Endpoints, Proxy-Fixes, blocked-content Tab

Paket A — Kritische Blocker:
- compliance_scope_routes.py: GET + POST UPSERT für sdk_states JSONB-Feld
- compliance/api/__init__.py: compliance_scope_router registriert
- import/route.ts: POST-Proxy für multipart/form-data Upload
- screening/route.ts: POST-Proxy für Dependency-File Upload

Paket B — Backend + UI:
- company_profile_routes.py: DELETE-Endpoint (DSGVO Art. 17)
- company-profile/route.ts: DELETE-Proxy
- company-profile/page.tsx: Profil-löschen-Button mit Bestätigungs-Dialog
- source-policy/pii-rules/[id]/route.ts: GET ergänzt
- source-policy/operations/[id]/route.ts: GET + DELETE ergänzt

Paket C — Tests + UI:
- test_compliance_scope_routes.py: 27 Tests (neu)
- test_import_routes.py: +36 Tests → 60 gesamt
- test_screening_routes.py: +28 Tests → 80+ gesamt
- source-policy/page.tsx: "Blockierte Inhalte" Tab mit Tabelle + Remove
