Title: Versioned DisplayPrefs and default sorts (#55741806)

This PR allows old, unusable DisplayPrefs objects to be blown away by enforcing a version number on them.
Also the sorts have been given a default by setting up the Sortable Widgets controller to scrape from a default list first, instead of just looking at what is already there.
Also the dashboard controller now starts the sortable widgets controller after building all the widgets, so they can be scraped.
