Build M1 Home for the mobile app

Hero card for the soonest upcoming event with a quick In/Out RSVP,
a "needs your answer" list, a season-dues card, and a news teaser --
all scoped to the person switcher's current selection. The RSVP quick
action posts to the (still placeholder-GET) event-detail URL that a
later screen (M2) will build out fully.
