feat: banques centrales (vote+dot plot+previsions), calendrier elargi, fix InvestingLive, M3 auto

Central bank governance (nouvel onglet Banques centrales) :
- lib/centralBankGovernance.ts + app/api/central-bank-sources : scraping live du
  vote de la derniere reunion, dot plot Fed (SEP), et desormais les previsions
  macro (PIB + inflation) publiees par chaque BC elle-meme (Fed SEP, Eurosystem
  staff projections, BoJ Outlook Report PDF, SNB conditional forecast, BoC MPR,
  RBA SMP). GBP/NZD laisses honnetement vides quand aucune source chiffree
  fiable n'est accessible (RBNZ bloque par Cloudflare).
- components/CentralBankSourcesTab.tsx : nouvel onglet avec cards par banque.

Taux directeurs + Money Supply M3 :
- data/rate_decisions.json corrige (JPY, EUR, NZD etc. etaient perimes d'1-2
  decisions) et desormais auto-maintenu : .github/workflows/update-rate-decisions.yml
  (horaire) detecte les changements de taux via Trading Economics et fait
  glisser current -> prev sans perte de donnee.
- data/money-supply-m3.json (nouveau) + .github/workflows/fetch-money-supply.yml
  (hebdo) : M3 par devise (proxy M2 pour l'USD, la Fed ne publiant plus M3
  depuis 2006), affiche dans CurrencyCard.

Calendrier economique elargi :
- lib/calendar-countries.ts, lib/calendar-taxonomy.ts, lib/fxstreetCalendar.ts :
  couverture pays elargie + classification des evenements + source FXStreet.

Fix InvestingLive :
- lib/investinglive.ts : l'ancienne API WordPress (wp-json) renvoyait 404 depuis
  leur migration Nuxt.js -> reecrit vers api.investinglive.com/api/homepage/articles,
  + fix crash silencieux (Tldr pas toujours un tableau).

Divers :
- .vercel/ ajoute au .gitignore (ne doit jamais etre commite, cf. son propre README).
- scripts/ (lancement PWA, push env Vercel), captures d'ecran, cache InvestingLive.
