Before: archiveTechFile called dsms.Archive() and discarded the result. The
file was archived to IPFS but no audit-trail entry was written, so there
was no way to later prove "this CE-Akte export went to DSMS with CID X".
After:
- archiveTechFile is now a method on IACEHandler with access to store + gin
context, and captures the CID from dsms.Archive().
- Writes an AuditAction "tech_file_export" audit entry whose new_values
JSON carries {cid, filename, size}, mirroring the Python evidence-upload
pattern.
- Applies to PDF, XLSX, DOCX, and Markdown exports.
Plus dsms package gets 3 unit tests pinning the contract: success-CID
extraction, gateway-unreachable returns nil, 500-response returns nil.
This closes DSMS Stufe 2 (evidence side was already wired; tech-file side
was missing the audit hook). Stufe 3 next: version chains + delta view.
