Bug 32743: Reindent the invoice details page

This patch reindents the invoice template so that it has consistent
indentation. These changes should have no visible effect on the page.

To test, apply the patch and go to Acquisitions -> Invoices.

- Perform a search which will return invoice results.
- Click on an invoice to view the details.
- Everything should look normal.

Viewing the diff while ignoring whitespace changes should show only
places where a line break was added.
