Web panel atl.page.metadata.banner does not appear in the space overview page

Issue Summary

The space overview and regular pages have similar layouts. The `
atl.footer` web panel appears in both the space overview and regular pages, however, the `atl.page.metadata.banner` appears only at the top of regular pages and not space overviews. Some apps need a web panel that appears in both locations.
