Migrate grateWizard from React/Next.js to native Nuxt integration

- Port all React components to Vue 3 (GwTabs, GwMN, GwCRA, GwCRS,
  GwMap, GwRelations, GwPerimeterList)
- Port hooks to Vue composables (useCesiumProfiles, useSavedPerimeters)
- Copy pure TS services and utils (duniter/, ss58, gratewizard utils)
- Add Leaflet + Geoman + MarkerCluster dependencies
- Serve grateWizard as popup via /gratewizard?popup (layout: false)
  and info page on /gratewizard (with Librodrome layout)
- Remove public/gratewizard-app/ static Next.js export
- Refine UI: compact tabs, buttons, inputs, cards, perimeter list
- Use Ğ1 breve everywhere, French locale for all dates and amounts
- Rename roles: vendeur→offre / acheteur→reçoit le produit ou service
- Rename prix→évaluation in all visible text
- Add calculated result column in CRA and CRS relation tables
- DU/Ğ1 selector uses toggle switch (same as role toggle)
- Auto-scroll to monetary data card on polygon selection
