JupyterViz: display simulation seed on screen so that the result can be recreated if needed

[rht]

What's the problem this feature will solve?
While the qualitative behavior of a simulation shouldn't depend on the seed, sometimes you'd observe a rare behavior that only a subset of the seed enables.

In Stable Diffusion UI, the seed is always necessary because the result wildly varies. Not sure whether displaying seed for ABM simulations would only add UI noise. I would personally always specify a seed for determinism.

We could have a collapsible model info that may contain not just the seed, but a JSON object (containing selected user input) that can be copied, and pasted in another session for quick recreation.
