Once we migrate existing MRs to have this column, we will be able to get the
latest diff for a single merge request more efficiently, and (more importantly)
get all latest diffs for a collection of MRs efficiently.

We already had this the other way around (merge_request_diffs.merge_request_id),
but this is needed to gather only the most recent diffs for a set of merge
requests.

 - Split layout from the styles of the row
 - Move command `.append-` `.prepend-` styles to bottom of source order
    - Actually applies styles over others in more situations which is
      probably what is expected when you add it to an element
    - Also allows us to get rid of some styles that were trying to get
      around this fact
