Fix theme toggle not persisting to localStorage in About page

[Copilot]

useTheme in About.tsx initialised dark mode state from localStorage but never wrote back on toggle, causing the About page's theme to diverge from the rest of the app on reload.

Change

Added the missing useEffect (+ import) to persist isDark — identical to the pattern already used in App.tsx and UserDashboard.tsx:

useEffect(() => {
  localStorage.setItem('string-theme', isDark ? 'dark' : 'light');
}, [isDark]);
