Report day outcomes (target hit / partial / loss) to the master

The reporter already computed targetHit per account to count it as
traded; now it also classifies each account that finished the day flat
and sends targetHit/partial/loss counts per firm and account type. A
realized loss reports as loss even on a grind day where any nonzero PnL
counts as done. Fields are additive, so an older master ignores them.
