Wave 7: Integrate JobDevTools into job detail page (FINAL)

- Task #18: Complete integration of all JobDevTools components
  - Updated job detail page (/jobs/[id]) with full JobDevTools UI
  - Connected SSE stream for real-time structured logs + metrics
  - Added crash-report and retry API routes for Next.js
  - Added format conversion for old/new log formats
  - Added DevTools links to JobsView modal and actions column
  - Wired up CrashReport retry with auto-fix parameters
  - Integrated SessionPanel for fingerprint display
  - Integrated MetricsDashboard for real-time charts

Job DevTools implementation complete: 18/18 tasks
