Put each client limit's count beside its "Limited" choice

The counts sat on a line of their own below the choices they belong to,
which also made the Advanced tab the tallest of the four and so decided
how much of the dialog the tab strip took. Each box now keeps its
natural height, and the free space collects below them.

Advanced went from 250px to 220px of preferred height, leaving the tab
strip about a third of the dialog rather than half.
