fix: SDK-Module Frontend-Backend-Mismatches beheben + fehlende Proxy-Routes

- P0: enableBackendSync=true in SDKProvider aktiviert (PostgreSQL State-Persistenz)
- P0: Source Policy 4 Tabs an Backend-Schema angepasst (is_active→active,
  data.logs→data.entries, is_allowed→allowed, rule_type→category, severity→action)
- P0: OperationsMatrixTab holt jetzt Sources+Operations separat und joint client-side
- P0: PIIRulesTab PII-Test auf client-side Regex umgestellt (kein Backend-Endpoint noetig)
- P1: GET Proxy-Routes fuer Import, Screening und UCCA [id] (GET+DELETE) erstellt
- P1: Compliance Scope ScopeOverviewTab/ScopeExportTab Prop-Interfaces erweitert
- P2: Company Profile speichert jetzt auch zum dedizierten Backend-Endpoint
- P2: UCCA Wizard von 5 auf 8 Steps erweitert (Rechtsgrundlage, Datentransfer, Vertraege)
