Bug 25473: Move JavaScript out of the footer of addorderiso2709.tt

This patch undoes the move of the JavaScript block to the footer made in
Bug 22734. The item information tab can include embedded JavaScript for
cataloging plugins, and these don't currently work with JS in the
footer.

To test, apply the patch and test the JavaScript driven features of the
"Add to basket from a staged file" page:

- Acquisitions -> Vendor -> Basket -> Add to basket from a staged file
  - MARC and Card previews, select all/clear all
  - Item information tab: Cataloging plugins for fields like
    date acquired, barcode
  - Default accounting details tab: Show inactive control
