feat(ui): use face-map layout for report zones and manual region picker; restrict manual care to smart mode

- scan-report: replace zone card grid with the same oval face-map layout as
  treatment-setup, zones tinted by recommended light with mode label; restore
  the per-light legend under the map
- manual-treatment: region picker now uses the same face-map layout
- manual care mode selection is smart-mode only: entry link hidden for
  non-subscribers and the page itself checks subscription (free mode passes
  since the backend reports it as active)
