Enhance frame processing with motion tracking in VideoEditor

Browse Source 
This commit updates the _process_frame_for_render method to include frame number handling for motion tracking. It allows the crop center to adjust dynamically based on tracked positions, improving the accuracy of cropping during video rendering. Additionally, debug statements have been added to provide insights into the motion tracking status and the positions of tracked points, enhancing the debugging experience for developers.
