Position Branding logo under thumbnail in search results

in app/views/catalog/_index.html.erb, the branding Image/text is displayed alongside some buttons.

we'd like to see how the logo would look positioned center-aligned with the thumbnail.

the thumbnail is rendered in app/views/catalog/_thumbnail.html.erb and it gets drawn in the template right after the _index template.

This shows an <img> tag for the branding:

<%= branding_image document %>

This shows the branding text:

<%= document.branding_note %>
