chore: reorganize project structure and prepare for deployment

- Organize files into logical directories (docs/, scripts/, tests/)
- Add comprehensive documentation (README, CONTRIBUTING, CHANGELOG)
- Create deployment automation scripts
- Add Docker production configuration
- Update .gitignore and add .dockerignore
- Remove temporary and test files from root
- Improve settings.py with DEBUG from env variable

Added:
- README.md with project overview
- CONTRIBUTING.md for contributors
- CHANGELOG.md for version tracking
- PROJECT_STATUS.md with current state
- docker-compose.prod.yml for production
- nginx.conf for production web server
- scripts/deploy.sh for automated deployment
- scripts/check-config.sh for configuration validation
- scripts/setup-ssl.sh for SSL certificate setup
- docs/DEPLOYMENT.md with detailed deployment guide
- docs/ENV_VARIABLES.md with all environment variables

Moved:
- Documentation to docs/
- Scripts to scripts/
- Test files to tests/

Removed:
- .history/ directory
- Test response JSON files from root
- settings_production.py (merged into settings.py)

This commit prepares the project for:
- Production deployment
- Team collaboration
- Docker containerization
- Proper documentation
