Add logout button on dashboard page

🚀 Pull Request

📋 Description

Added a Logout button on the dashboard. Clicking the button removes accessToken and refreshToken from localStorage, calls the backend logout API with credentials, and redirects the user to the login page.

Note: Make sure to set VITE_BACKEND_URL in your .env file before running the frontend.
