feat(iace): expandable detail comparison in benchmark tab

Backend: HazardSummary now includes description, scenario, possible_harm,
trigger_event, and mitigations[] for side-by-side comparison.

Frontend: Each matched pair row is now clickable/expandable showing
two-column detail view:
- Left (GT): hazard type, cause, zone, lifecycle phases, risk values
  (F/W/P/S->R), residual risk, measures, type (KM/TM/BI), norms, comment
- Right (Engine): name, scenario, zone, possible harm, trigger, measures
