invalid web extension management

Attempting to delete a non-existent web extension path.

Traceback (most recent call last):

FileNotFoundError: [Errno 2] No such file or directory: '/home/me/git/ComfyUI/web/extensions/ComfyUI_3dPoseEditor'

And instead of copying to the actual path of the web extension, it is recommended to use the following approach:
