- Move /admin/import/* tools under /admin/studio/* and add studio nav, layout and tabs
- Add shared catalog maintenance panel plus a /admin/studio/maintenance tab
- Make furnidata reconciliation overwrite conflicting entries with the
DB-authoritative items_base classname/id (surfaced via fixedConflicts)
- Add furnidata_translate_enabled setting to skip the heavy localized
furnidata build during import (manual build-languages still forces it)
- Update staff smoke contract test for the studio hub
The danger confirm button used a hardcoded text-white class which failed the
admin theme source audit and could render unreadable against custom admin
themes. Switch to the semantic text-destructive-foreground token.
Also add media-grid.tsx to the graphical allowlist: its overlay badge sits
on top of arbitrary user images, so a fixed white-on-dark overlay is
intentional and not theme-chrome.
Restores the full test suite to green (303/303).
