feat(train): Home opens on this week, its totals and its seven days (ADR 0030, D60)

The week's time, distance and workouts above Home's list, and a strip of
its days, each as tall as the time trained on it, starting on the day the
person's language starts weeks on. Home's empty hint points to the Record
tab, where its button had gone.
