The upload grid was its own scroll container (max-height + overflow on the
same element). Firefox sizes auto grid rows to min-content in that setup,
so every tile collapsed to its footer height and the image was clipped to a
wide strip; Chromium sizes them to max-content, which is why this only
showed up in the user's browser. auto-rows-max pins rows to max-content in
both; verified with headless Firefox screenshots and Chromium measurements
(60 tiles render 152x194 each, 1845px of content in a 639px scroller).
The box is now 70vh so it behaves as a proper fixed gallery area with its
own scrollbar instead of shrinking with the item count.
IQDB progress: the page header now shows a live 'Checking IQDB — x/y'
counter with a bar while background checks run, so the queue is visible
without opening the per-file modal (which keeps its spinner, candidates
and per-file errors).
