fix: Vorbereitung-Module auf 100% — Feld-Fixes, Backend-Persistenz, Endpoints

- ScopeExportTab: 11 Feldnamen-Mismatches gegen ScopeDecision Interface korrigiert
  (level→determinedLevel, riskScore→risk_score, hardTriggers→triggeredHardTriggers,
  depthDescription→depth, effortEstimate→estimatedEffort, isMandatory→required,
  triggeredByHardTrigger→triggeredBy, effortDays→estimatedEffort)
- Company Profile: GET vom Backend beim Mount, snake_case→camelCase, SDK State Fallback
- Modules: Aktivierung/Deaktivierung ans Backend schreiben (activate/deactivate Endpoints)
- Obligations: Explizites Fehler-Banner statt stiller Fallback bei Backend-Fehler
- Source Policy: BlockedContentDB Model + GET /api/v1/admin/blocked-content Endpoint
- Import: Offline-Modus Label fuer Backend-Fallback
