test(insights): write the status goldens with sorted keys

The goldens held their fields in the order the code assigned them. They are now written with every object's keys sorted, so the text depends only on content and diffs and compresses well; the parsed content of every golden is unchanged. They carry no clock reading or generated id: the clock is pinned and the ids are fixed.
