add pipeline job management with /jobs pages and per-step output viewer

- Pipeline jobs now persist to DB with progress tracking and cost accumulation
- Jobs survive WebSocket disconnects with in-memory event buffer replay
- New /jobs list page with search, status badges, and cost display
- New /jobs/:id detail page with live WebSocket attachment and REST fallback
- Two-column layout using WorkspaceLayout for resizable steps/output panels
- Streaming messages tagged with stepIndex/iterationLabel for per-step output grouping
- TaskRunnerModal links to job detail page once job is created
- Dock entry added for Jobs page
