Pick rest time on a 1-second wheel

Replaces the 5-second Steppers in Settings and the routine editor's
custom-rest row with a shared SecondsWheelRow: the row shows the value
and tapping it expands an inline wheel (10-180s, 1s steps) beneath.

 **July 2026**
 
+Rest time is now set on a wheel with one-second precision — in Settings and in a routine's custom rest — instead of a 5-second stepper.
+
 A live status panel between the timer and the figure now shows heart rate (with the target color cues, in much larger type), HR zone, calories, and workout time.
 
 A new Library tab puts your routines and the exercise library one tap away instead of buried in Settings.
