- Fixed total_return_pct, profit_factor, n_bars showing 0 in detail view
by using ?? operator instead of || 0 and fixing renderDetail logic
- Run Backtest now renders result directly from API response
(no re-fetch race condition)
- Redesigned UI: monospace trading terminal aesthetic
- Darker palette (#090d14 background, #0d1321 cards)
- Indigo histogram, proper grid layout
- Subtle borders (1px #1a2332), better spacing
- Status indicator with pulse animation
- Sidebar shows Sharpe, Return%, Profit Factor per result
- 8 metric cards: Return, Sharpe, DD, Win Rate, PF, Trades,
End Equity, Sortino
- Smaller, cleaner fonts, monospace throughout
- Bumped memory guard to 2GB to prevent dashboard getting killed
