feat(iace): DSMS-CID-Badge im Tech-File-Export + aggregierter Bulk-Diff
Punkt 1 — UI-CID-Badge nach erfolgreichem Tech-File-Export:
- archiveTechFile setzt X-DSMS-CID / X-DSMS-Filename / X-DSMS-Size response
  headers + Access-Control-Expose-Headers, sobald DSMS-Archive durchlief
- Split iace_handler_techfile.go (war ueber 500 LOC) → archiveTechFile lebt
  jetzt in iace_handler_techfile_archive.go, setDSMSResponseHeaders als
  pure Helper mit 3 unit tests
- Next.js IACE-Proxy forwarded die X-DSMS-* Header und erkennt jetzt auch
  XLSX/DOCX/MD als Binary-Response (vorher nur PDF/ZIP/octet-stream)
- ExportCIDBadge.tsx zeigt CID, Filename, Groesse + Kopieren-Button +
  "Verlauf anzeigen" (oeffnet CIDHistoryModal)

Punkt 2 — Bulk-Diff Report V1 → V_latest:
- Neuer Endpoint GET /api/v1/documents/{cid}/bulk-diff im dsms-gateway:
  laeuft parent_cid-Kette ab, berechnet chronologische Step-Diffs,
  aggregiert Totals (added/removed lines, metadata_fields_changed,
  binary_steps). Edge-Cases: einzelne Version, binaere Steps, abgebrochene
  Kette
- BulkDiffPanel.tsx zeigt 4-Stat-Header + Step-Tabelle
- CIDHistoryModal bekommt Toggle-Button "Bulk-Diff V1 → V_latest anzeigen"
  neben dem Versions-Counter; damit auch vom IACE-Export-Badge erreichbar

Tests: 3 neue Go-Tests, 4 neue pytest-Tests, alle gruen

// archiveTechFile stores a tech-file export to DSMS (best-effort, non-blocking)
// AND records the resulting CID in the IACE audit trail so the export is
// traceable. The "new_values" JSON carries the CID + filename so the audit
// timeline can later resolve the CID against the DSMS gateway for verify.
//
// Side-effect: when the archive succeeds, X-DSMS-CID / X-DSMS-Filename /
// X-DSMS-Size response headers are attached so the frontend can render an
// inline CID-badge directly in the export-success path (no separate audit
// query needed). Headers are written before c.Data() and survive the binary
