Give the closest capsule the rounded rect whenever it wraps

The capsule's shape was keyed to the verdict's declared line count, so
"Closest station" — one declared line — always drew as a Capsule while
its text wrapped to two lines in the row's narrow column, leaving the
semicircular ends crowding the words they wrapped. Saves never showed
this because its amount line makes the declared count two.

The shape now follows the DRAWN height: a GeometryReader behind the
text block reports what it actually rendered, divided by the caption's
line height taken through ScaledMetric so the test holds at every
Dynamic Type size. One drawn line keeps the capsule; two or more get
the same 8pt rounded rect the other verdicts use. The first layout
pass, before there is a height, falls back to the declared count.
