fix(views): keep a post visible when its only figure is an unconfirmed occurrence (I4)

hasActivity only checked carriedIn/allocation/charges, so an archived post
whose sole activity this month was an unconfirmed recurring occurrence
(zero remaining, nonzero expected/projected) was dropped from
monthView.rows — its Projected figure never reached the month view even
though ExpectedBand listed the same occurrence. remaining and projected
are both fully derived from five raw fields; the check now covers all
five.
