feat: Phase 5 — DB persistence for scan results + Phase 10 in plan

- Migration 086: compliance_agent_scans table (findings, services, corrections)
- agent_history_routes.py: POST /scans (save), GET /scans (list), GET /scans/{id}
- Scan results survive page reloads and can be reviewed later
- Phase 10 (Playwright website scanner) added to product roadmap
