🌓 feat(ui): add auto theme mode, refactor ThemeToggle, optimize header theme handling
- Feature: Introduce 'auto' theme mode
- Detect system preference via matchMedia('(prefers-color-scheme: dark)')
- Add useActualTheme context to expose the effective theme ('light'|'dark')
- Persist selected mode in localStorage ('theme-mode') with 'auto' as default
- Apply/remove `dark` class on <html> and sync `theme-mode` on <body>
- Broadcast effective theme to iframes
- UI: Redesign ThemeToggle with Dropdown items and custom highlight
- Replace non-existent IconMonitor with IconRefresh
- Use Dropdown.Menu + Dropdown.Item with built-in icon prop
- Selected state uses custom background highlight; hover state preserved
- Remove checkmark; selection relies on background styling
- Current button icon reflects selected mode
- Performance: reduce re-renders and unnecessary effects
- Memoize theme options and current button icon (useMemo)
- Simplify handleThemeToggle to accept only explicit modes ('light'|'dark'|'auto')
- Minimize useEffect dependencies; remove unrelated deps
- Header: streamline useHeaderBar
- Use useActualTheme for iframe theme messaging
- Remove unused statusDispatch
- Remove isNewYear from theme effect dependencies
- Home: send effective theme (useActualTheme) to external content iframes
- i18n: add/enhance theme-related copy in locales (en/zh)
- Chore: minor code cleanup and consistency
- Improve readability and maintainability
- Lint clean; no functional regressions
