feat(docker): add async port change and docker compose reload for services

- Introduce async `change_port` to update service port and reload docker compose
- Add `run_docker_command` for running docker compose commands asynchronously
- Implement `_get_random_port` utility for selecting available ports
- Refactor service discovery and port change logic to use new async methods
- Update proxy and manager logic to support new port change workflow
