Bug 33588: Add page-section to inventory tool items list

The table with items created by the inventory tool was
missing the page-section class and therefore had no
white background.

To test:
* Go to cataloguing > inventory
* When you don't have a lot of data: just submit the form
* Look at the result list, confirm missing white background
* Apply patch
* Confirm the background is now correct
