fix: chat PlayerName fallback + nouveau build WebGL 20260517b

- ChatUI: PlayerName utilise PlayerPrefs comme fallback si non connecte
- NetworkManager: sauvegarde le nom dans PlayerPrefs a la connexion
- GameCanvas: version build bump -> 20260517b (cache bust)
- Nouveaux fichiers build_mai (data + wasm mis a jour)
