Copilot 3980b9e580 Fix IDOR in exports by adding token verification (Issue #31637) (#32883)
* Fix IDOR in exports by adding token verification

Implement jdleesmiller's suggested fix for Issue #31637:
- V1: Return export token in create response
- V1: Verify token in get_export using secure_compare
- Web: Pass token through fetchExport and fetchDownload
- Web: Return token from exportProject to frontend
- Frontend: Pass token as query param on status/download requests
- Add tests for both services

Fix window.location.pathname to .href to preserve query params

Code review correctly identified that window.location.pathname strips
query parameters. Switch to window.location.href so the token query
parameter is preserved in download URLs.
