Well, in terms of the entire wiki, it hasn't been imported yet. I see you added an import in your personal JS however you are importing the wrong script. You are importing u:dev:MediaWiki:Status/code.js which is for this script; not the one you linked to. As stated in the instructions, you want to import u:dev:MediaWiki:UserStatus/UCP.js. That is, assuming you linked to the correct script. Also, make sure you have enabled personal JS in your preferences.
