Add Motion

The supported motion engines in the HeyGen Interface are Runway Gen-3, Runway Gen-4, Minimax Hailuo 1, Minimax Hailuo 2, and Kling. Legacy motion types such as veo2, seedance_lite, and avatar_iv are not available in the UI.
Among these, veo2 and seedance remain functional through the API only, while avatar_iv is not supported and will return the error message:
