LP1869898 Angular staff cat place hold from patron

The place hold button in the patron holds list now takes staff to the
Angular catalog for holds placement.  A banner is displayed along the
top of the catalog to indicate which patron the hold is for and to
provide a link back to the patron's holds list.
