Render the campaign analysis in the report drawer: status row for
generating (5s polling), failed (error + retry) and empty states, then
the structured result — overall callout, problem cards with severity
tags and evidence chips linking to run reports, per-scenario narratives
and priority-sorted suggestions. Generate buttons are terminal-only with
guidance when no analysis model is configured.
Embed compact progress (completed/planned total + overall pass_rate,
reusing the report's aggregation) into GET /campaigns so the list drops
its N+1 report fetch. Poll list and open report drawer every 5s while the
tab is active and a campaign is still running. Show scenario version and
trigger source tags in the child-run drill-down.
