fix(wtp-udock w324): pages publiques sans pills + dock centre sur internes

CAUSE RACINE (capture Yacine 18:05 sur /solution-finder.html):
1. Pills WTP/IA Hub/Master/Orch/WevCode/Arena/Droid/Admin/WEVIA Engine
   visibles top-right sur /solution-finder.html = page PUBLIQUE
   = leak info interne aux visiteurs
2. AMBRE-V1-PUBLIC-GUARD existait deja MAIS whitelist incomplete
   (manquait solution-finder, products, proofs, trust-center, etc.)
3. Sur pages internes, dock top-right chevauche autres widgets BR/TR

FIX wave 324:
1. _AMBRE_PUBLIC_PATHS etendu +13 pages publiques:
   solution-finder, about, contact, products, pricing, legal, privacy,
   terms, trust-center, case-studies, proofs/index, blog, landing
2. _AMBRE_PUBLIC_PREFIXES NEW: protection par prefixe URL
   /products/* /docs/* /help/* /blog/* /proofs/* /landing/* /case/*
   /legal/* /static/* /public/*
   = toutes les sous-pages publiques auto-exclues du dock
3. W324 CSS dock-centering injecte par script:
   - #opus-xlinks/#wtp-udock/#v130-xnav: position fixed top:8px left:50%
   - transform translateX(-50%) = CENTRE haut au lieu top-right
   - z-index 9998 (sous notifications)
   - rgba bg + backdrop-blur premium
   - border indigo WTP
   - flex-wrap nowrap + overflow-x scroll si trop de pills
   - mobile: top->bottom (passe en barre du bas)

Resultat:
- Pages publiques (solution-finder, products, etc) = ZERO pills
- Pages internes (master, cockpit, etc) = pills CENTREES haut
  + plus aucun chevauchement avec widgets BR/TR

Zero regression (str_replace surgical, CSS additive)
chattr +i toggle, GOLD backup
CF purge wtp-unified-dock.js + solution-finder

Doctrine zero overlap UX + zero leak info interne sur pages publiques
