[FIX] stock: location barcode more than one page

Since 3d04e4488, several pages have to be denoted by:

  `<div class="article" />`

And not as previously:

  `<div class="page" />`

This was not taken into account in the "Location BarCode" report so we
had only one page of barcode (so 4 barcodes since there is 4 barcode by
page) displayed.

fixes #19698
opw-1817574
closes #24098
