Docker stats (healthy, RAM, CPU...) integration

### Description

I would like to have the same feature that exist in https://gethomepage.dev to display the memory and CPU usage of each container. Very useful to check if everything is OK and which container to stop. Might be hidden by default.

In fact, I might work on this if I have some time :)

Thank you for this project, I chose it because it is more extensible than https://gethomepage.dev and consumes less memory for my little server (26.2MiB vs 133.8MiB)

No source file, test, or entry point is named in the issue. Start by locating the existing Docker integration and the dashboard component that renders container information, then compare the requested healthy, RAM, and CPU data with the referenced gethomepage feature. Done means displaying those container stats, with the option to hide them by default, and covering the behavior with tests where the project supports them.
