fix(v14-abf): toggle cols cacher seulement bidirectionnel + revert pastels transparent + footer align

- YAML carte-o-source : label central -> 'Une medecine du corps social pour
  ecrire un nouveau contrat social' (phrase pleine 3 lignes)
- YAML : projet TMIP gagne lien_central:true (edge explicite centre <-> projet)
- build-carte-o.js : addEdge accepte opts.central=true pour tagger les edges
  rattachees au noeud central (permet tuning force-link cote Vue)
- carte-o.json regenere : 17 nodes, 20 edges (vs 19 V1.2-O), tous les edges
  central->thematiques + central->tmip portent flag central:true
- CarteO.vue : noeud central rendu en RECT 300x64 fill encre (vs cercle r30),
  label blanc multi-tspan 3 lignes 13px font-weight 500 line-height 1.35
- CarteO.vue : splitCentralLabel reecrit pour wrap intelligent (3 lignes
  ~30 chars), preserve compat ' + ' (V1.2)
- CarteO.vue : force tuning V1.3 -> alphaDecay 0.025, velocityDecay 0.4,
  forceCollide +12 (CENTRAL_COLLIDE_RADIUS=160 pour le rect), forceX/Y
  strength 0.05 rappel cadre, link distance/strength differencies
  (central->projet = 90/0.6, central->essai = 200/0.3)
- CarteO.vue : hover handler selector etendu rect|circle
- CarteOWrapper.vue : CarteEdge gagne champ central?:boolean
- ColCentre.astro : tabs Chatbot retires (ChatbotV2 import retire aussi),
  remplaces par header bandeau 'Sommaire editorial d'architecture
  d'ecologie politique' (gauche, monospace 12px) + legende 3 symboles
  (publie ● / a venir ○ / projet 🟠) en droite
