Login api for frontend, and docker containerized deployment

[MaxWutw]

This pull request introduces a complete Docker-based setup for the QuestFantasy backend, along with a token-authenticated user registration and login API. It includes Docker configuration, environment variable management, a custom authentication system with token expiration, and API endpoints for user registration, login, logout, and profile retrieval. The changes also update project documentation with detailed setup and usage instructions.

Dockerization and Deployment:

• Added a Dockerfile for building the backend image, an entrypoint.sh script to manage migrations and server startup, and a docker-compose.yml file to orchestrate the Django app and PostgreSQL database, enabling easy local development and deployment. (Dockerfile, entrypoint.sh, docker-compose.yml) [1] [2] [3]
• Updated .dockerignore to exclude unnecessary files from Docker builds. (.dockerignore)

Environment and Settings Management:

• Updated .env.example with safer defaults, added TOKEN_TTL_SECONDS for token expiration, and changed the default database host for Docker compatibility. (.env.example)
• Modified config/settings.py to support both PostgreSQL and fallback to SQLite, added Django and DRF settings for authentication, and configured token expiration. (config/settings.py) [1] [2] [3] [4]

Authentication and User API:

• Implemented a custom ExpiringTokenAuthentication class to enforce server-side token expiration. (accounts/authentication.py)
• Added serializers for user registration and login, enforcing password validation and unique email checks. (accounts/serializers.py)
• Created API views for registration, login, logout, and profile retrieval, with endpoints exposed under /api/auth/. (accounts/views.py, accounts/urls.py, config/urls.py) [1] [2] [3]
• Registered the accounts app in Django and added its configuration. (accounts/apps.py, config/settings.py) [1] [2]

Documentation:

• Added a comprehensive README.md with setup, Docker installation, environment configuration, and usage instructions. (README.md)
