The header's "matched" subtotal used the FIFO round-trip sum, which doesn't
equal the broker's average-cost day P&L while positions are partially open — so
"matched + open" never tied to the headline day P&L (e.g. -1340 + open vs the
broker's -627).
Show broker-authoritative realized instead: matched = day P&L - open unrealized,
so matched + open == day P&L by construction. Per-trade rows stay FIFO-accurate
(each is a real fill pair); only the header subtotal is broker-truth. Factor the
open-unrealized sum into a shared helper used by both the live board and the
`journal` close capture. Falls back to the FIFO sum when no equity snapshot
exists.
Verified live: board + journal both reconcile (matched + open == day P&L).
Tests: 3 new (reconciliation invariant + FIFO fallback).
