Timers: "to 9:30a" under a countdown-to-time, smaller status lines, titles that fit

A ProPresenter count_down_to_time timer's detail line reads "to 9:30a"
(or "to 21:30" on a 24-hour clock) instead of a sentence. The status and
detail lines under the digits are drawn at 0.8 of the title's size, and
fit() budgets them at that share. A title that would be cut off shrinks
to fit its card (measured off-screen, down to 8 px) instead of ending in
an ellipsis; a changed label re-fits.
