Enhance crop application with motion tracking in VideoEditor

Browse Source 
This commit updates the crop functionality to incorporate motion tracking offsets, ensuring that the crop center aligns with tracked points when motion tracking is enabled. It also refines the handling of crop adjustments and display offsets, improving the overall user experience during video editing. Additionally, the key mappings for expanding crop dimensions have been corrected for clarity in user interactions.
