feat(geoportal): one-time setup banner for PostGIS views

- GET /api/geoportal/setup-views checks if zoom views exist
- POST creates them (idempotent)
- SetupBanner component: auto-checks on mount, shows amber banner if
  views missing, button to create them, success message with docker
  restart reminder, auto-hides when everything is ready
