refactor: standardize port to 1999 across all files

- Updated default port from 8080 to 1999 in config, Docker, and documentation files
- Modified example URLs and test commands to use new port
- Ensured consistent port references in environment configs and deployment examples
- Updated health check endpoints in Docker and testing scripts

The port change aligns with LIV Golf port allocation standards for staging environments (5000-9999 range).
