Add collapse/expand of telemetry sections

[elijahbenizzy]

Is your feature request related to a problem? Please describe.
Sometimes we want to collapse the graph/results area, and sometimes we want to display it all.

Describe the solution you'd like
Minimizing different parts -- one idea:

See the screenshot below -- you'll want to:

1. Add the ability to collapse the graph view (step view should take up the whole side)
2. Add the ability to collapse the step list (should make the graph view take up the whole left side)
3. Add the ability to minimize the state area (should make the left side take up the whole part.

You'll have to look at the Layout here (which we set to one of them -- may want to make it reactive.

Alternatives -- you could use dragging to reposition it (although without a state-ssaving dashboard it's less fun).

Additional context

Good first issue for a frontend expert to get started on Burr.
