Closes#1003.
#999 centralised the attribution so branding_hide_powered_by is honoured
everywhere, but GalleryLayout kept its own inline guard. The gallery footer
therefore still flashed — it kept `!brandingSettings?.hide_powered_by`, where
undefined is falsy, so a white-labelled instance briefly showed the attribution
on first paint, on the surface a white-label customer is most likely to see.
And there were two implementations of one rule, which is the bug class #999
existed to close.
The footer appends the attribution to its copyright line inside an existing
<p>, so a straight swap would nest a <p> in a <p>. Added an inline variant
rendering a <span> that carries the leading ' | ' itself: the separator belongs
to the component, since a caller placing its own would have to repeat the
visibility guard to avoid leaving a dangling separator when the attribution is
hidden.
No extra request — GalleryView already uses usePublicSettings(), the same hook
and react-query key, so the cache is shared. The footer also picks up
common.poweredBy, so it is translated rather than hardcoded English.
Removes the now-unread hide_powered_by from GalleryLayout's prop type and the
mapping feeding it in GalleryView.
Four cases cover the variant — span not paragraph, separator present, separator
hidden with the attribution when white-labelled, hidden while loading. Each was
checked against the pre-fix shape: rendering a <p> or moving the separator out
breaks one.
