Bug 39499: Add some padding to the Save button in the sticky bar in cataloging

This patch corrects a regression in the style of the floating toolbar on
the basic MARC editor page. There should be comfortable padding around
the "Save" button while keeping the toolbar's full width matching the
tab panels.

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

- Go to Cataloging -> New record.
- The toolbar with the "Save" button should look correct.
- The container with the tab buttons right below that should be the same
  width as the tab panel.
- Scroll down and confirm that everything looks good when the toolbar is
  floating.
