Bug 37046: Use template wrapper for OPAC curbside pickup tabs

This patch updates the OPAC curbside pickups template to use WRAPPERs
for the Bootstrap tabs markup.

To test, apply the patch and enable the "CurbsidePickup" system
preference if necessary.

- Log in to the OPAC and click the "Curbside pickups" tab in the sidebar
  of the user summary page.
  - With no curbside pickup policy defined, you shoul see a single tab,
    "Your pickups" and the message "No curbside pickups."
- In the staff interface go to Administration -> Curbside pickup.
  - Configure curbside pickups for at least one branch.
- Return to the OPAC and refresh the curbside pickups page.
  - You should now see a "Schedule a pickup" tab along with the "Your
    pickups" tab, and it should be active by default.
  - Schedule a pickup.
    - When the page refreshes, the "Your pickups" tab should now be
      active by default.
