Enhance snapping functionality in VideoEditor to include line snapping

Browse Source 
This commit improves the snapping feature in the VideoEditor class by adding the ability to snap new tracking points to the closest point on the line segment between consecutive tracking points, in addition to existing point snapping. The distance calculation logic has been refined, and the specification has been updated to reflect the new snapping behavior, which now operates within a 10px radius for both point and line snapping, enhancing the precision of motion tracking.
