Comment 5 for bug 2019207

I have tested this code with a back port to 3.7.4 and with the latest main branch on production data.

It works for me, so I've pushed a signoff branch: user/dyrcona/lp2019207_patron_view_discovery_layer_url-signoff (https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/dyrcona/lp2019207_patron_view_discovery_layer_url-signoff).

There was a conflict in Open-ILS/src/eg2/src/app/staff/catalog/record/actions.component.html that I resolved by restoring the button component inside the anchor tag. I believe that button is necessary for internationalization.

Other staff at CW MARS have tested the feature on 3.7.4 and we plan to use this in production soon.

I've added the pullrequest and signedoff tags to indicate that I think this code is ready to go. Since it touches Angular, I'd like another set of eyes on it before it goes in.
