The desktop feedback-filter chips (All/Likes/Saved/Rated/Commented)
were nested inside the categories row conditional, and the standalone
fallback block is lg:hidden — so a gallery without photo categories
(the default) rendered no feedback filter at all on desktop, despite
the docs and a fully working filter implementation behind it.
Render the row whenever either part has content and gate only the
category scroller on categories existing. The media-count label hides
below lg when no categories exist so the mobile layout stays unchanged
(mobile keeps its own chip block). With-categories galleries render
identically to before.
Regression test pins both chip groups in the DOM with and without
categories (fails on the pre-fix component).
