feat(dsms): Stufe 1 — Gap-Analyse Report wird in DSMS archiviert

- Go DSMS Client (internal/dsms/client.go): Archive() + Verify()
- Python DSMS Client (compliance/services/dsms_client.py): archive_to_dsms() + verify_dsms()
- Gap-Analyse AnalyzeProject() archiviert Report-JSON nach DSMS
- Response enthält dsms_cid wenn Archivierung erfolgreich
- Frontend: Grünes "Revisionssicher archiviert" Badge mit CID im GapDashboard
- DSMS Proxy Route (/api/sdk/v1/dsms/[...path]) für Verify-Abfragen

Stufe 2 (Evidence Upload → DSMS) und Stufe 3 (Version Chains) folgen.
