add auth system: users, login, JWT, protected routes

Domain: User entity, AuthPort/PasswordHashPort/SecretStore ports.
Adapters: auth (argon2 hashing, JWT tokens), secret-store (env-based),
config-sqlite user repository, http-api auth routes + extractors.
Application: auth_service. SPA: login page, auth client, protected router.
