Bug 34567: Correct colors for advanced cataloging editor status bar

This patch updates the advanced cataloging editor CSS so that the
"status bar" footer below the editor has colors consistent with the
staff interface redesign.

To test, apply the patch and clear your browser cache if necessary.

- Enable the EnableAdvancedCatalogingEditor preference if necessary.
- Go to Cataloging -> Advanced editor.
- At the bottom of the screen below the editor the "status bar" should
  have a green border that matches color in the header search bar.
