Adds document count to ActionBar

[allanlasser]

This closes #465 by adding a document count back to the ActionBar.

In the process of updating the component, I decoupled it from state with an itermediate ActionBarContainer.

I also updated some styling and created a Storybook for testing.

To review, please approve the new components in our Chromatic Storybook and examine the preview deployment for correct look and behavior.

For some reason, I'm not seeing the action bar at all. No pagination, no menus.

How do I do that? Right now the preview is missing the menu and paginator entirely.

Looks like the loading value is not updating correctly, fixed that.
