Enhance backtesting with dynamic position sizing and ATR-based SL/TP

```

The commit introduces significant improvements to the backtesting functionality:

1. Added dynamic position sizing based on risk percentage
2. Implemented ATR-based stop loss and take profit calculations
3. Enhanced backtest state management with detailed trade tracking
4. Updated database schema to store additional backtest metrics
5. Modified UI components to display new backtest results
6. Added logging and error handling improvements
7. Removed the London Breakout strategy from the codebase

These changes improve the depth and accuracy of backtesting while providing more comprehensive performance metrics.
