Enhancement: UI for Story Budget collapsing categories

[mikeyarce]

Expected/Desired Behavior

In Edit Flow > Story Budget, there is a list of post categories and under each one you'll see a list of posts scheduled for those categories.

If you click on the title of the category, you see a "move" cursor like this:

However, when you click on the category, it just collapses any content inside of it.

I would expect:

1. No "move" cursor since that's not what happens
2. Some sort of UI element that let's me know this is a collapse-able region - maybe like a down arrow?
3. I would expect if nothing is in the category, probably don't need to collapse? The CSS also looks odd when collapsed as it has more padding on top than bottom.

Actual Behavior

Collapsed item seems like it has weird padding:

How does the plugin/feature/module currently work.

Steps to Reproduce the Problem

1. Go to Dashboard > Story Budget
2. Click on a category to see it collapse
