feat(train): Home opens on today's figures from the band (ADR 0030, D60)

While the Loop gave figures for today, Home shows them above the week:
steps, active time, last night's sleep and Nightly Recharge, as Profile
lists a day, tapped opening the day's page. Shown above Home's message
too, before a first workout; the week waits for one.
