Feature: Specifying source for undo / redo

[hectoreccles]

Summary

This pull request refactors the undo/redo methods to allow you to specify a source. The following changes were made:

• Renamed parameters for the change method from source and dest to sourceStack and destStack.
• Added new source parameter for the change method with the EmitterSource type.
• Refactored undo and redo methods to leverage the updated change method while maintaining backward compatibility.

Motivation

These changes make the undo/redo methods more flexible, particularly in cases where you want to undo or redo actions while user interaction is disabled.

Testing

• Verified that undo/redo functionality behaves as expected in the editor.
• Confirmed backward compatibility with existing workflows.

Please review the changes and let me know if any adjustments are needed. Also this is my first ever PR so apologizes if I have done anything wrong.
