Bug 31028: Add ability to report catalog concerns from the OPAC

This patch adds the ability for patrons to report catalog concerns via
the opac.

Test plan
1) Enable the new `OpacCatalogConcerns` system preference
2) Navigate to the record details page of a biblio record on the OPAC
3) You should see a new 'Report a concern' option in the right side
   actions box
4) If not logged in you should have the login modal displayed and upon a
   successful login you should be redirected back to the details page
   with a new model displayed for entering concern details
5) Submit your concern with a title and details.
