change the .nav-category height to min-height about hospitalrun-frontend

Yeah I struggled a bit with how to work this out when I was mocking it up, because a min-height will break the flow of the cards then, as so:

I ended up settling on using overflow: scroll, but the challenge then is that you don't know there are more options unless you actually scroll.

I'm going to try out using overflow: scroll again as a fix, and set the height so that it will at least show some of one of the next buttons. That will provide a visual indicator that there are more options. We can always iterate on the visual indicator later, and if it turns out that hiding some options at all behind a scroll behavior is a bad idea I can rethink this approach later.

So basically FYI I'm punting on the UX of this piece for now by implementing the scroll thing.

Cards with additional nav items beyond view look like this for now:
