fix(search): keep the map list's count and sort on one line

Beside the map, "19 schools within 1.0 miles of SW196AR" (359px) and the
sort menu (281px, as wide as its longest option) could not share the
pane's 427px, so the sort dropped to a second line.

In the map view the heading now reads "19 schools within 1 mile": the
postcode is already in the search box just above, and the radius reads
as the toolbar's does. The sort menu is capped at 11rem, truncating a
long choice, and the header no longer wraps; on a narrow pane the count
truncates rather than pushing the sort down. List view keeps the full
heading. Tried on staging by injecting the change: 243px + 176px, one
line at 1440.
