Auth : mode prototype factice en prod + fix test DB manquante

- Login : panneau proto-mode en avant quand DEMO_MODE actif (profils API)
  masque le formulaire extension-required ; note trustWallet à venir
- auth.ts : TODO trustWallet avec protocole postMessage prévu
- routers/auth.py : TODO trustWallet au point de vérification signature
- test_middleware : fixture _create_tables (autouse) — ASGITransport ne
  déclenche pas le lifespan, init_db() ne tournait pas → duniter_identities
  introuvable au verify ; 224/224 passent
