Tag meanings are brighter and slightly larger, and the top bar picks
their language (Simplified/Traditional Chinese, Japanese, Korean,
Russian, Spanish, French, German, Portuguese, or none) for every
interface language; the old Chinese switch carries over. Typed text in
any language that is not plain English is translated to English, and
translating a box's foreign tags drops one whose English is already
there. The backend skips DeepL for targets it does not take instead of
falling back to English, and lets MyMemory detect other sources.
Unused prompt helpers in translation_service.js are removed.
