feat: add sleep tracking features with leaderboard and user authentication

- Implemented a new HomePage component displaying the leaderboard.
- Created Providers component for session management using next-auth.
- Developed Header component for navigation and user authentication.
- Added Leaderboard component to fetch and display sleep data.
- Introduced SleepCard component for individual sleep entries.
- Created SleepForm component for logging sleep data with manual input options.
- Added SleepPhaseBar component to visualize sleep phases.
- Implemented utility functions for formatting and calculating sleep data.
- Set up authentication with Discord using next-auth and Prisma.
- Configured middleware for protected routes.
- Added TypeScript definitions for next-auth session.
- Configured Tailwind CSS for styling.
- Initialized TypeScript configuration for the project.
