fix: Profil-State nach Backend-Load in SDK-Context sync + alle Tests fixen

- Company Profile: setCompanyProfile() und COMPLETE_STEP dispatch nach Backend-Load,
  damit Sidebar-Checkmarks nach Refresh erhalten bleiben
- compliance-scope-engine.test.ts: Property-Namen anpassen (composite_score, risk_score, etc.)
- dsfa/types.test.ts: 9 Sections (0-8), 7 required, 2 optional
- api-client.test.ts: SDKApiClient-Klasse statt nicht-existierendem Singleton
- types.test.ts: use-case-assessment statt use-case-workshop
- vitest.config.ts: E2E-Verzeichnis aus Vitest excluden
