dev!: balance: Use DayPartition for multibalance reports.

This allows us to guarantee that the report periods are well-formed and
don't contain errors (e.g. empty spans, spans not contiguous, spans not
a partition).

Note the underlying representation is now for disjoint spans, whereas
previously the end date of a span was equal to the start date of the
next span, and then was adjusted backwards one day when needed.
