- New IQDB card on local item pages: fetches the signed raw file, POSTs it
to e621's /iqdb_queries.json with the user's credentials, and lists
candidates as tiles (thumbnail, rating, score%) with exact-MD5 markers.
- Selecting a candidate opens a detail panel (rating, score, favs, size,
tag preview) and linking is an explicit confirm that reuses the e621
match endpoint; videos show a note since IQDB is image-only.
- Guests don't see the card; linking follows the uploader/staff rule.
