fix(ui): Fix language setting display showing 'false*' instead of lan…

…guage name

- Extend getDisplayValue function to support string type settings
- Add LANGUAGE_DISPLAY_NAMES mapping for friendly display names
- Language setting now shows 'English', '中文', etc. instead of 'false*'
- Fix type assumptions in getDisplayValue (was boolean-only)
- Improve user experience for string-based settings

Fixes UI issue where language setting displayed incorrect boolean value
instead of the actual selected language name.
