conserve screen real-estate when embedding logs into trace view

[codefromthecrypt]

I have a hard time seeing the log data due to screen displacement.

• I expect in the trace view, there will be no difference between the current trace ID and those of the logs, so I think we can remove this column.
• Also, if the service name matches, which it should, we can remove that one.
• More optionally, if there is no severity (common in data I have seen from log events), we can remove that, too.
