'Sign Up' First, Instead of 'Sign In' first

The base44.auth.redirectToLogin() directs users to a combined login/sign-up page. We need a way to redirect new users directly to the sign-up form not the login form. This will improve conversion rates for new user acquisition. Users coming from a "Get Started" call-to-action expect to create an account, not log in. We'd like a base44.auth.redirectToSignup() method, or an optional parameter like redirectToLogin({ mode: 'signup' }) that defaults the authentication page to the sign-up view.
