feat(v12-o): Carte O logos plateforme via Brandfetch CDN (visible zoom>1.5x)

Champ optionnel domain dans YAML carte-o-source : propage vers JSON et
permet d'afficher un logo plateforme en bas-droite de chaque node (cercle
blanc 18px + image clippee circulaire 14px) quand le zoom depasse 1.5x.

V1.2-O par defaut : substack.com sur les 15 thematiques essais. Centre +
projet TMIP gardent leur fill brut (encre / ocre). Toggle visibilite via
callback zoom (opacity 0/1 sur .logo-overlay).

A flagger : CDN Brandfetch retourne 403 en curl server-side avec le client
ID fourni. A revalider en browser (origin trans-former.fr) — le CDN peut
exiger un Origin header autorise. Si bloque, fallback prevu en V1.3
(proxy local ou logos packages dans /public/logos/).

Files:
- public/data/carte-o-source.yaml : +15 champs domain
- scripts/build-carte-o.js : propagation domain -> JSON
- src/components/vue/CarteO.vue : CarteNode.domain + logoUrl helper
  + logo-overlay (circle + image clip-path) + toggle visibilite zoom
- public/data/carte-o.json : regenere (15/17 nodes ont domain)
