LP1852782 Linker links to auth record editor

Adds a new UI at /staff/cat/authority/edit/ for finding authority
records by ID and editing authority records via the Angular MARC editor.

Modifies the "Cataloging" => "Retrieve Authority Record By ID" nav menu
entry to point to the Angular version of the interface.

Augments the MARC edit authority linking dialog to turn authority ID's
into links which open the authority record in its own MARC editor in a
new tab.

Misc. MARC editor repairs related to loading authority records by ID.
