Fix language switcher to preserve current page path

- Update language switcher to translate current page path instead of redirecting to root
- When switching languages, preserve the page you're on (e.g., /articles/ → /it/articles/)
- Works for both desktop header and mobile hamburger menu
- Uses Hugo's string functions to manipulate URL paths
