Logout Button Not Visible & Logout Not Working

## Description:
The logout button is missing from the UI, and as a result, users are unable to log out. Even if the button is manually triggered, logout functionality is not working as expected.

## Expected Behavior:
- The Logout button should be visible in the appropriate place (e.g., navbar or dropdown).
- Clicking Logout should log the user out and redirect them to the login page.
- The session/token should be cleared properly.
