feat(dashboard): Add dynamic work status column for convoys

The status column now shows computed work status based on progress and activity:
- "complete" (green) - all tracked items are done
- "active" (green) - recent polecat activity (within 1 min)
- "stale" (yellow) - older activity (1-5 min)
- "stuck" (red) - stale activity (5+ min)
- "waiting" (gray) - no assignee/activity

Previously the status column always showed "open" since we only fetch
open convoys, making it static and uninformative.

Changes:
- templates.go: Add WorkStatus field to ConvoyRow, add workStatusClass func
- fetcher.go: Add calculateWorkStatus() to compute status from progress/activity
- convoy.html: Add work status badge styling, use WorkStatus in table
