Bug 33082: Add yellow buttons and page sections to 'copy order' pages

When creating a new order from an existing order (copy),
there was no page section on the search results and the
submit buttons were not yellow (primary).

To test:
1. Make sure you have budgets, funds and vendors
2. In Acquisitions, search for a vendor
3. Create a basket
4. Add an order to that basket (Order from new (empty) record is easiest)
5. Add to the basket again, choosing the "From existing orders (copy)" option
6. Search for you previous order
7. The table of ordres has no white background (missing page-section) and
   the "Next" button is not yellow
8. Check the order and click Next
9. The "Duplicate orders" button is not yellow
10. Apply patch
11. Verify buttons are now yellow and the table has a white background
