complete paper trading: auto-close on stop/target + My Trades realized record

resolve_open_trades walks the daily bars after each open trade and closes it at
the target (target hit) or stop (stop/ambiguous), leaving undecided trades open.
Runs nightly inside the outcome evaluator (so it's coordinated with fresh OHLCV)
and on its manual trigger. New "My Trades" section at the top of Signals → Track
Record shows realized hit-rate, expectancy (avg R), total R, total P&L, and a
closed-trades table — your actual results, separate from the theoretical signal
record below it.
