Bug 31927: Use bigger font-size for bibliographic information on staff details page

This patch removes the adusted font size from the definition of the
.results_summary spans. The percentage decrease was being multiplied
with another rule.

To test, apply the patch and rebuild the staff interface CSS.

Locate a bibliographic record in the staff client and view the detail
page. Confirm that the bibliographic information is displayed in a
comfortable size.

Also test that catalog search results still look correct.
