As per Sebastien,
- more padding for "No more users" case.
- update text styles for both "Add user" and "No more users".

Also,
- fix active user name font weight (Medium->Normal)
- don't make the "no more users" label a button (it already didn't do
  anything when you clicked it, but there's no sense in making it a
  button).
