Require Home minutes_total and Supply run label for every list (review H1)

parseTonight now rejects a tonight dinner without the minutes_total key
instead of reading it as null; an explicit null is still valid. The Home
API always emits the key. parseShoppingList checks the label against
weekStart for unready lists too, since the API supplies it regardless of
readiness.
