#63 enh: logout button

Add a logout button under the settings button on the left panel.

@fszontagh I'm starting work on this issue now! I'll add a logout button under the settings button in the left panel. This will involve:

1. Finding the settings button location in the left panel
2. Adding a logout button below it
3. Implementing the logout functionality using the AuthContext
4. Testing the logout flow

Starting implementation now.

✅ Implementation completed!

I've successfully added a logout button under the settings button in the left panel.

Changes made:

1. Modified AppSidebar.tsx:
   • Added LogOut icon import from lucide-react
   • Integrated useAuth hook to access the logout function
   • Added logout button in the SidebarFooter below the Settings section
   • Styled the button to match the existing UI theme (slate colors, hover effects)

Features:

• ✨ Logout button appears directly under the Settings section
• 🎨 Consistent styling with the rest of the sidebar
• 🖱️ Hover effect on the button for better UX
• 🔒 Uses the existing logout() function from AuthContext which:
  • Clears session data from localStorage
  • Updates authentication state
  • Redirects to the login page

The changes have been committed and pushed to the repository (commit aaaef97).

@fszontagh The feature is ready for testing!
