Bug 35880: Use template wrapper for accordions: Patrons requesting modifications

This patch updates the patrons requesting modification page so that
Bootstrap accordion markup is generated by WRAPPERs.

To test, apply the patch and make sure you have the OPACPatronDetails
system preference enabled.

- Create at least two different patron modification requests:
  - Log in to the OPAC using two different patron accounts, each time
    following the sidebar link for "Personal details."
  - Make some changes to the patron records and submit them.
- In the staff interface, from the home page, click the "Patrons
  requesting modifications" link.
- You should see the list of updates in the same format as before:
  Collapsible panels where clicking the patron name heading expands the
  corresponding information.
- View the detail or checkout page for one of your updated patrons.
  - Click the "Review pending modifications" link.
  - The modifications page should open with that patron's information
    exapanded.
