Authenticate routes.

[jakevanhalder]

This pull request guards routes with authentication and closes issue #20.

Key Changes:

• backend/musicRecommendationService/urls.py: Added a logout/ route.
• backend/musicRecommendationService/views.py: Added logout_view to clear the Django session and return a JSON success response.
• frontend/src/middleware.ts: New middleware that protects authenticated routes (currently /music-map).
• frontend/src/app/services/lastfm_user.ts: Added logoutUser() which calls the backend logout/ endpoint.
• frontend/src/lib/components/Navbar.tsx: Updated signOut() to call logoutUser(), clear client-side auth state, remove local storage, and redirect appropriately.
• frontend/src/app/login/lastfm-callback/page.tsx: Improved Last.fm callback flow (async/await, error handling, and redirect logic).

Frontend file moves/renames

• Multiple files relocated into the frontend/ directory (UI components, assets, configs, etc.).
