Refactor tracking point management in VideoEditor and MotionTracker to ensure accurate display coordinates

Browse Source 
This commit modifies the handling of tracking points in the VideoEditor and MotionTracker classes by removing the storage of display coordinates. Instead, display coordinates are now calculated dynamically during rendering, ensuring accuracy regardless of crop or rotation states. The changes enhance the consistency of point transformations and improve logging for better debugging and verification of coordinate accuracy during mouse interactions.
