fix(11-02): repair broken text strings from mass CSS variable replacement

The mass find-and-replace incorrectly replaced the word 'surface' in
human-readable text strings and type literals, not just CSS class contexts.
Fixed: App.tsx control surface text, DocumentCenter knowledge base text,
i18n en.ts, and Panel tone prop type literal.
