Increase character limit on Job summary edits to remove clunky view of summary edits in the audit trail of a job

When CSRs are editing the summary on the job page, if the summary edits exceed a certain character limit, the edits appear as clunky bubbles in the job audit trail. These extend the audit trail significantly and it is difficult for the CSR to view the full edit of the summary because they have to scroll within the bubble that has been created by exceeding the character limit. I think this would be solved by either a) increasing the character limit when editing a summary or b) changing the view on the summary edits completely in the job audit trail.
