LPS-50443 - Migrate Layout Prototypes portlet aui-base javascript

Hi Rob,

Attached is an update for https://issues.liferay.com/browse/LPS-50443.

There was an existing issue with the reset button in merge_alert.jsp.  It was getting bound with a selector using the wrong namespace.  I removed the random namespace as it already receives the portlet namespace from the button taglib.

Please let me know if there are any issues.

Thanks!
