Tests for the log's fields and the metrics Grafana reads (#403)

Browse Source 
Three tests for what the dashboard and the alert rules read and nothing
checked: every ipx_ metric named in grafana/dashboard.py and alerts.py
(read out of them at compile time) is served by render, with the ones
written only once known (counts, the last scan, a job under way) set
first; ipx's JSON log lines for a scan's events carry ev, feed, new,
bytes, msg and error.type, and inside a span trace_id and span_id; the
directory's snapshot line carries instance, accepted and the refused_
counts.

The JSON layer was built the same way in both services' setup; it is
otel::json_layer now, so the tests run the layer production does.

The log tests set the global subscriber, as production does: under a
scoped one WithTrace finds no current span (#408).
