branding_hide_powered_by only hid the attribution on the main gallery footer. It
stayed visible on the gallery password screen, client access page, Premium
layout, admin and customer login, accept-invite and CMS pages — AdminLoginPage
rendered it unconditionally with no guard at all, so the setting genuinely did
not apply there.
Routes those surfaces through one <PoweredBy /> component in components/common
that reads the public setting itself (the DynamicFavicon pattern) and renders
nothing when white-labeling is on, including while the settings are still
loading so a white-labelled instance never flashes the attribution.
Also collapses three duplicate translation keys (gallery.poweredBy,
adminLogin.poweredBy, customer.login.poweredBy) into a single common.poweredBy,
and translates pages that had 'Powered by' hardcoded in English across all 8
locales.
Fork-PR workflows were never approved so CI did not run. Verified locally
against cf243b44: tsc --noEmit clean, ESLint clean, vitest 124 passed across 24
files, and npm run build succeeds.
GalleryLayout.tsx keeps its own inline guard and is not routed through the new
component; tracked separately.
