Refactor authentication and session management

- Removed session-based user retrieval from dependencies.py and main.py.
- Eliminated SessionMiddleware and related session handling code.
- Updated dashboard and team views to directly query user data from the database.
- Simplified redeem and team management views to remove authentication checks.
- Adjusted templates to reflect changes in user context handling.
- Added camera selection feature in scan_qr.html for improved QR code scanning.
- Cleaned up Docker configuration and requirements for better deployment.
