Login redirects to /dashboard/ but framework ships no Dashboard page; new hosts 404 on first authenticated load #95

Summary

After a successful login through the bundled users module, Login.tsx redirects to /dashboard/:

// users/pages/Login.tsx:37
new URLSearchParams(window.location.search).get('next') || '/dashboard/'

But neither the users module nor the host scaffold registers a route at /dashboard/, so a freshly scaffolded sm new --preset full app shows 404 the moment a user logs in.

Resolved in commit ade3e24 (PR #98). users.login_redirect_url is now a configurable module setting; Login.tsx reads it from shared props and falls back gracefully when the dashboard module isn't installed.
