The ListObjectVersions API was receiving key-marker and version-id-marker
parameters but not using them to filter results. This caused infinite
pagination loops when clients tried to paginate through results.
Fix by adding filtering logic after sorting:
- Skip versions with key < keyMarker (already returned in previous pages)
- For key == keyMarker, skip versions with versionId >= versionIdMarker
- Include versions with key > keyMarker or (key == keyMarker and versionId < versionIdMarker)
This respects the S3 sort order (key ascending, versionId descending for same key)
and correctly returns only versions that come AFTER the marker position.
