Dé-Replit-isation complète du projet

Supprimés :
- replit.md — doc Replit obsolète
- docs/GITEA_TUTO.md — tuto push Replit → Gitea (obsolète)
- artifacts/api-server/ — serveur TypeScript mort, remplacé par Flask
- artifacts/voix-du-peuple/vite.config.selfhost.ts — fusionné dans vite.config.ts

Nettoyés :
- ai_agent.py — fallback Replit AI supprimé (Mistral + OpenAI-compatible suffisent)
- vite.config.ts — plugins @replit/* retirés, PORT optionnel (défaut 5173)
- package.json + pnpm-workspace.yaml — @replit/* retirés du catalog et des deps
- badge.tsx + button.tsx — commentaires // @replit supprimés
- README.md, DEPLOIEMENT.md, DAT.md, DEX.md, WIKI.md — références Replit remplacées
