feat(studio): localize catalog studio UI and polish responsive layout

Route all Catalog Studio strings through the admin.studio namespace
(workspace, filters, review, inspector, quality, sync, scale32, organize
imports and page titles/subtitles) with English fallback, and add shared
StudioPage chrome plus a loading skeleton. Tighten mobile padding on the
header and sub-bars.
