fix(docker): simplify deployment with nginx fixes and alternative compose config

- Update nginx/default.conf with complete configuration including events section
- Add docker-compose-simple.yml for simplified deployment without nginx
- Update docker-compose.yml to properly mount nginx configuration
- Revise DOCKER_FIX.md with clearer instructions and recommended solutions
- Provide three deployment variants: with nginx, without nginx (recommended), and quick fix
- Include data folder structure and environment setup documentation
This change addresses nginx configuration errors and FileNotFoundError by providing both a corrected nginx setup and a simplified alternative deployment method without nginx for faster troubleshooting and deployment.
