Changes:
- Save selected language to localStorage when user switches languages
- On page load with clean URL: check localStorage and load saved language preference
- If no localStorage preference exists, default to server's language choice
- Update language button active states based on localStorage preference
- Keep URLs clean (no lang parameter added) while maintaining language choice
- If URL has lang parameter, save it to localStorage for consistency
How it works:
1. Visit / (clean) → Shows English (default)
2. Switch to Spanish → Saves 'es' to localStorage, loads Spanish content
3. Click logo (clean URL /) → Page loads, checks localStorage, loads Spanish
4. Language persists across clean URL navigations via localStorage
This solves: Clean URLs + Language persistence
