chore: remove ~100 debug console.log statements from frontend

Cleaned up verbose debug logging left from development:
- AdvancedChart.tsx: removed ~50 debug logs (time parsing, order fetching, marker creation)
- ChartWithOrders.tsx: removed debug logs and unused klineMinTime/klineMaxTime variables
- ChartWithOrdersSimple.tsx: removed data loading debug logs
- ChartTabs.tsx: removed render/selection debug logs
- ComparisonChart.tsx: removed equity history debug logs
- AITradersPage.tsx: removed 🔥 DEBUG logs from handleSaveEditTrader
- App.tsx: removed mount debug log

Kept legitimate console.error/console.warn for actual error handling.
