feat(train): Profile opens on your body, the last 12 weeks and this year (ADR 0030, D60)

Above the days: a card with your body's weight and resting and maximal
heart rate, tapped opening Your body; the last 12 weeks' time trained as
bars, a week tapped showing its time, distance and workouts; and this
calendar year by activity. Home's week card reads its time as the days do.
