Bug 33464: Add page-section to "Orders by fund" result list

This updates the results table for the "Orders by fund"
report with the common white background.

To test:
* Go to Reports > Orders by fund
* Search for orders (you might have to add one)
* Verify the results table is missing the common
  white background
* Appyl patch
* Reload page and verify styling is improved
