This pull request introduces user authentication and authorization to the frontend, improves the navigation experience, and adds support for creating, editing, and deleting challenges. It also sets up a local PostgreSQL database for the backend using Docker Compose. The most significant changes are grouped below.

Authentication & Authorization:

• Added an AuthProvider context (frontend/src/context/AuthContext.jsx) to manage user login, registration, and logout, storing credentials in localStorage. Components can access user state and authentication actions via useAuth.
• Updated the Axios API setup (frontend/src/api/axios.js) to attach authentication credentials from localStorage to each request.
• Protected challenge-related routes in the app (frontend/src/App.jsx) so only authenticated users can access them.

Navigation & UI Improvements:

• Added a reusable NavBar component that displays navigation links, the logged-in user's name, and a logout button; integrated it into main pages. [1] [2] [3] [4]
• Updated the challenge list page to show which challenges the user has passed and to include a "+ New Challenge" button for creating challenges. [1] [2]

Challenge Management:

• Added pages and routes for creating and editing challenges, and enabled challenge authors/admins to edit or delete their challenges from the challenge page. [1] [2]

Backend & Local Development Setup:

• Added a PostgreSQL service to docker-compose.yml with persistent storage and a health check; configured the backend to use it. [1] [2]
• Added a .dockerignore file for the frontend to speed up Docker builds and avoid copying unnecessary files.

Development Environment:

• Updated VSCode settings to enable interactive Java build configuration updates.
