Refactor stickman rig and ragdoll mechanics; enhance pose restoration and stability

Browse Source 
- Disabled constraints for the stickman rig's head bone to allow for smoother animations.
- Improved mode transitions in the sandbox stage to preserve stickman poses between EDIT and DIRECT modes.
- Added side profile stabilization for knee bends in the ragdoll component to prevent unnatural poses during physics interactions.
- Enhanced the snap-to-standing functionality to restore the stickman's original pose accurately.
- Introduced new tests for validating pose preservation during mode transitions and ragdoll behavior during walking animations.
- Created a new scene for testing stickman bending and ragdoll transitions.
