Fit the settings sheet on the screen again

Adding the presets heading pushed the sheet past the bottom of the
screen. It was closer to the edge than it looked: at 390x844 the old
content cleared the bottom by 10px, so 49px of new row tipped it over.

Height alone couldn't fix it. Measured in real viewports the content was
733px at 390 wide and 750px at 375 — and a 375x667 phone is 667px tall,
so on that screen no max-height reaches the content at all. It had to get
shorter. Raising the cap 88dvh -> 92dvh does the rest, and stops there:
the scrim is what you tap to dismiss (scrim's click handler closes
whichever sheet is open), and the sheet's top padding is a flat 8px with
no safe-area inset, so a full-height sheet would tuck the grab handle
under the notch.

Trimmed the row padding 16 -> 14, the grab handle, the Done margin and
padding, the hint margin and the presets gap: content down to 685px at
390 wide, which clears the top of the screen by 159px. The two smallest
phone sizes still scroll, by 88px at 375x667 — the rest of the fat there
is description text wrapping to three lines in the narrow left column,
which needs the copy or the row layout changed, not more spacing.

The score sheet shares .row and got the same trim: 466px, fits at every
size tested.
