Display package identifiers in Agreements UI

Purpose:
Where a package has identifiers these should be displayed at the end of the package information in the e-resource view pane (same as title identifiers already display)

Specifically the following identifers/namespaces should be included:

• ISIL (namespace = isil)

• ZDB (Package) (namespace = zdb-pkg)

• EZB (Collection) (namespace = ezb-collection-id)

• E-Book Pool (namespace = ebp-id-pkg)

• GOKb ID (namespace = gokb_id)

• GOKb UUID (namespace = gokb_uuid)

Only display labels where a value exists for the identifier namespace

Also add the IDs to the bottom of the Package display card used in Agreement lines to show the identifiers as already happens for titles:

Example of title with identifiers for reference:
