Bug 10493: (follow-up) fix minor template issues

This template followup fixes some minor template errors and adds some
style to dialog buttons matching those seen on the circulation page.

To test, submit barcodes to trigger the various error conditions:
Non-existant barcode, over the renew limit, restricted patron, item on
hold. Override and Ignore buttons should be properly styled and
functional.
