feat(cannaiq): Add Workers Dashboard and visibility tracking

Workers Dashboard:
- New /workers route with two-pane layout
- Workers table showing Alice, Henry, Bella, Oscar with role badges
- Run history with visibility stats (lost/restored counts)
- "Run Now" action to trigger workers immediately

Migrations:
- 057: Add visibility tracking columns (visibility_lost, visibility_lost_at, visibility_restored_at)
- 058: Add ID resolution columns for Henry worker
- 059: Add job queue columns (max_retries, retry_count, worker_id, locked_at, locked_by)

Backend fixes:
- Add httpStatus to CrawlResult interface for error classification
- Fix pool.ts typing for event listener
- Update completeJob to accept visibility stats in metadata

Frontend fixes:
- Fix NationalDashboard crash with safe formatMoney helper
- Fix OrchestratorDashboard/Stores StoreInfo type mismatches
- Add workerName/workerRole to getDutchieAZSchedules API type
