Description of the issue: As was done for all other Page/Post Types (Story,
PRs, etc) the Campaign Page Type should have a Refined Results page
designed.

e.g. https://www.greenpeace.org/international/story/

Even though this Page Type still needs to be integrated with the rest of
the site, the style for the Campaign Refined Results page is missing and
should be fixed. wmorrisj
