Update environment configuration and clean up unused files

- Added `KERNELBOT_ENV` variable to `.env.docker.example`, `.env.example`, and `.env.railway.example` to specify the environment.
- Enabled `ACL_CATALOG_ENABLED` in the environment files for production readiness.
- Removed multiple unused audit image files and cleaned up `.gitignore` to exclude unnecessary directories.
- Updated health check command in `docker-compose.yml` for better compatibility with dynamic port settings.
- Enhanced documentation links in `README.md` for clearer setup instructions and deployment guidelines.
