With several strategies the header cards showed only the first one. Expose day_pnl and drawdown_pct per strategy and add aggregateStatus() (frontend) so the cards show the whole account: summed cash/equity/P&L/trades/positions, worst drawdown, and any halt. Single-strategy runs are unchanged. Adds tests.
