Subject: [PATCH] Implement precision error handling in MakerPointsEngine

- Added a new `isPrecisionError` function to identify precision-related errors in the error utility module.
- Updated the MakerPointsEngine to handle precision errors by logging warnings and synchronizing precision when such errors occur during order processing and stop-loss execution.
- Enhanced the `syncPrecision` method to allow forced synchronization, improving the handling of precision-related issues.
