[7.2] Show Docker container MAC addresses

[elibosley]

Summary

• Backports the Docker container MAC address display fix from master to 7.2.
• Passes endpoint MAC addresses through the Docker client/container data path and renders them with the existing container IP details.
• Keeps MAC display hidden when no running container endpoint value exists.

Why

The 7.2 Docker container list did not expose assigned MAC addresses, making it hard to confirm fixed or runtime endpoint MACs from the UI.

Validation

• php -l emhttp/plugins/dynamix.docker.manager/include/DockerClient.php
• php -l emhttp/plugins/dynamix.docker.manager/include/DockerContainers.php
• git diff --check origin/7.2..HEAD
