PR Title: Implement Protected Route Redirection

Description

• Added logic in ProtectedLayout to redirect users to the login page if they are not authenticated.
• Utilized useEffect to monitor the isLoggedIn state from the useAuth hook.
• Prevented the rendering of protected components when the user is not logged in, enhancing security and user experience.

Changes Made

• Updated ProtectedLayout to include authentication check and redirection.
• Ensured that protected routes are only accessible to logged-in users.
