feat(i18n): full i18n for all pages + sidebar lang switcher + zh-TW locale

- All pages now use t() for internationalization
- Sidebar footer: searchable upward dropdown language switcher
- Generated zh-TW.json (Traditional Chinese) via gen-locales.cjs
- CSS for lang switcher with mobile/collapsed sidebar support
- Removed language toggle from settings page
