LP#1752891 Crowded text on Print Item Labels page fix.

This patch replaces an h4 style used for labels for dropdown lists, removes a blue background, and changes the style of the title of the page. All to make this page look more consistent with other pages in Evergreen.  Also removes some unnecessary extra divs and makes the bootstrap columns for the top form more consistent.
