Add ability to sort the jobs in the paperless shop scheduled jobs screen

Client would like to be able to sort the jobs listed in the scheduled jobs screen in Paperless Shop. Currently this list is sorted by paperless shop line priority, which means that a vehicle with several open jobs, may have it’s jobs scattered among the list, causing a mechanic to miss or ignore jobs while the vehicle is in the bay that they could also work on and close out.

The trick is in allowing users to sort, without allowing them to get around priorities set by upline managers.
