Plot processing graph
I updated admin-ui with the new `Processing graph` tab with `Plot processing graph` button. I wasn't sure that the plot would have appropriate size by default for all screens so I added sliders for width and height:

I doesn't look very nice but okay for the first version? 
I also updated some requirements, specifically `gradio`, because the old version of `gradio` wasn't rendering plots well.

I think it was a bad idea to update `poetry.lock` because now it has all the `libcommon` (from local path) dependencies. Maybe remove it completely from this directory? In the ui `libcommon` is installed from git, main branch.
