Overhaul of ps command

[marcelldls]

This PR tries to do the following for ec ps:

• Eliminates the charts that are shown which are not services - fixes ec ps -a showing "epics-pvcs"  #101
• Return consistent information between local and k8s domains by adding restarts, running status, image information
• Replaces pandas with polars. Improves pip install time from 50s to 20s and solves return alignment issues.

I had to change the podman/docker ps -o to be json rather than customised table as docker does not support getting the restart information - which had the benefit of removing the need for a regex for version information and makes it easier to get labels.

In order to get consistency with the status I decided to just have a bool for "running" since this differs between k8s and podman/docker
