feat(journal): show aggregate header for date + record (#1542)

This commit implements the date and record aggregates in the Posting Journal.  I have used MIN for
the aggregation, though MAX would work as well.  Ultimately, no choice would make sense if the
column contains non-uniform information.  These columns are expected to have uniform values.
