fix(miku): correct scale + animation playback

- Fixed Blender export: remove FBX armature modifier before scaling,
  then transform_apply(scale=True) before creating new armature
- Model now exports at correct 1.8 unit height (verified in Blender)
- SkinnedPlayerModel now polls MovementStateMachine in _process
  to drive animations based on movement state
- Player 1 gets Miku at origin, others get procedural humanoid at y=-0.9
