API uses latest re-upload author instead of original submission author #448
Description
Problem:
Wiki Loves competitions demand that the original file upload date and the original author are credited for an entry, regardless of subsequent file overwrites or re-uploads.
Currently, loaders.py::make_entry extracts img_timestamp and img_user as the primary dataset.
Impact:
When a file is flagged as a re-upload (oi_archive_name is present), Montage incorrectly credits the newest author and timestamp, which breaks competition disqualification rules (e.g. dq_by_upload_date).
Proposed Solution:
When oi_archive_name indicates a previous version exists, make_entry must extract rec_img_timestamp and rec_img_user as the primary entry data, and route the newer img_ variables strictly to the flags["reupload"] dictionary.
