Bug 33187: Use template wrapper for tabs article requests and holds awaiting pickup pages

This patch updates the article requests management and holds awaiting
pickup templates in the staff interface so that they use the new WRAPPER
directive for building tabs.

To test, apply the patch and make sure the ArticleRequests system
preference is enabled.

- Go to Circulation -> Article requests
- You should see three tabs, "New," "Pending," and "Processing."
- The tabs should look correct and work correctly.
- Go to Circulation -> Holds awaiting pickup
- You should see three tabs, "Holds waiting", "Holds waiting over X
  days," and "Holds with cancellation requests." ("X" is the value in
  the ReservesMaxPickUpDelay system preference)
