feat: Prompt Mode / DL Mode split in the popup

- DL Mode button: one click harvests everything on screen (click ⋮ -> hover
  Download -> click 1K, verified per tile), click again to stop after current
  tile; no queue involved, no server reporting for manual runs
- Prompt Mode = the existing queue runner, relabelled
- harvestActive synced to storage so the popup button reflects state
