Add click animations to actor editor

Play a one-shot gesture animation when clicking an actor, matching the
in-game LegoEntity::ClickAnimation behavior (objectId = m_move + 10).
After the click animation finishes, the walking loop resumes. Adds the
4 click animations from SNDANIM.SI to the asset manifest and extends
ActorRenderer with queue-based click animation playback. Also fixes
treadmill XZ stripping for click animations where actor_01 is nested
under wrapper nodes.
