Track Class Lock block in Workflows

A new Track Class Lock block is now available in Workflows. It locks the class label of each tracked object by majority voting, removing the class flicker you get when a model alternates between similar classes for the same physical object across video frames.

Wire it in after a tracking block such as Byte Tracker. Once a class collects enough high-confidence votes and leads the runner-up, it locks, and the block writes that class into every later detection of the track. It can also carry a lock through short occlusions by reattaching to a new tracker ID where the object reappears, which produces cleaner counts and steadier demos.
