Pinning it to the header's right edge read fine on a narrow window and stranded
it on a wide one — it's a status, but it's still part of the pill row. It now
follows the search bar.
Its tooltip was the long explanation of the counts, which is redundant next to a
popover that spells them out and overflowed the viewport from the right edge.
The chip gets the counts themselves; the explanation moves onto the popover's
counts row, where there's room for it.
