feat: per-import translation toggle and language picker in studio

Furni imports can now choose whether to translate (per import) and which
languages to build, instead of always rebuilding all 13 FurnitureData_<lang>
files. The studio header also has a global switch that persists the
furnidata_translate_enabled setting, seeding the per-import default.
