Add 6 Recharts charts in a collapsible Historical Trends panel on the
Compliance page, covering all Tier-1 recommendations from the reporting
design doc.
Backend — 5 new API endpoints:
- GET /api/compliance/trends — active totals + per-team counts per upload
- GET /api/compliance/mttr — mean days to resolution per team
- GET /api/compliance/top-recurring — most persistent active findings by seen_count
- GET /api/compliance/category-trend — category breakdown per upload (future use)
- GET /api/archer-tickets/status-trend — ticket pipeline by creation date + status
Frontend — new ComplianceChartsPanel component:
- Active Findings Over Time (multi-line: total + per-team dashed)
- Change per Report Cycle (stacked bar: new/recurring + resolved)
- Team Compliance Health (multi-line per team)
- Mean Time to Resolution (horizontal bar per team)
- Most Persistent Findings (horizontal bar top-10 by seen_count)
- Archer Exception Pipeline (stacked bar by date + status)
All charts degrade gracefully to a no-data placeholder until uploads
accumulate. Panel is collapsible to stay out of the way when not needed.
Adds recharts dependency to frontend.
