fix(ui): fix NaNd ago - return full QueueItem from POST /api/queue + defensive relTime

- POST /api/queue now returns the full QueueItem (with createdAt, phases, etc.)
  instead of a stripped {id,url,status,enqueuedAt} subset
- TimelineRow.relTime() now handles undefined/NaN gracefully, falls back to 'just now'
- TimelineRow timestamp uses item.createdAt ?? item.enqueuedAt as fallback
