LP1615805 No inputs after submit in patron search (Angular)

Updates the source order of the Angular Circulation patron search form's
reset and submit buttons to the end so that no input fields appear after
the submit button, as required for accessibility. This results in an
awkward tabbing order for sighted users, but is intended as an interim
step toward better accessibility while we rethink the overall design of
the form.

The visual layout of the form has not changed at desktop sizes, but
there are now phone and tablet layouts as well.

Release-note: Moves submit button to end of Angular patron search form
