Bug 30384: Reindent template for ordering from a MARC file

This patch updates the template for ordering from a MARC file so that
the indentation is consistent.

This patch does not fix a couple of bugs which will be fixed in a later
patch: The MARC modal window has the wrong width, and there is a
Flatpickr error in the console.

To test apply the patch and go to Acquisitions -> Vendor -> Basket ->
Add to basket -> From a staged file.

- Click "Add orders" next to the staged file you want to use.
- On the "Add orders" page, test that everything still works correctly:
- Tabs work correctly
- JavaScript controls (select all, show inactive, etc.) work
- MARC and Card previews work
- Adding orders works
