Implement Backtesting & Chart Replay in PF1

Users should be able to test strategies and practice execution using a built-in Backtesting and Chart Replay feature. This would allow them to replay historical price data, simulate trades under realistic market conditions, and evaluate performance before committing capital in live accounts.

By adding backtesting and replay, PF1 would provide traders with a safe and practical way to validate their approach, reduce costly execution errors, and improve consistency over time. This would make PF1 not only a live trading and management tool, but also a complete environment for learning, practicing, and refining strategies.
