feat(freigabe): Import/Screening/Modules/RAG — API-Tests, Migration 031, Bug-Fix

- import_routes: GET /gap-analysis/{document_id} implementiert
- import_routes: Bug-Fix — gap_analysis_result vor try-Block initialisiert
  (verhindert UnboundLocalError bei DB-Fehler)
- test_import_routes: 21 neue API-Endpoint-Tests (59 total, alle grün)
- test_screening_routes: 18 neue API-Endpoint-Tests (74 total, alle grün)
- 031_modules.sql: Migration für compliance_service_modules,
  compliance_module_regulations, compliance_module_risks
- test_module_routes: 20 neue Tests für Module-Registry-Routen (alle grün)
- freigabe-module.md: MkDocs-Seite für Import/Screening/Modules/RAG
- mkdocs.yml: Nav-Eintrag "Freigabe-Module (Paket 2)"

Gesamt: 146 neue Tests, alle bestanden
