Can't replace /admin/create-first-user view

[benjaminpreiss]

Describe the Bug

Seems I can't replace the /admin/create-first-user view. So this isn't working:

admin: {
    components: {
      views: {
        'create-first-user': {
          Component: '@/components/CreateFirstUser',
          path: '/create-first-user',
          exact: true,
        },
      },
    },

It still renders the old UI in place. For the plugin I am building (a better-auth integration) it is key to be able to also replace the existing routes.

Reproduction Steps

1. npm install
2. npm run dev
3. Visit the browser, localhost:3000/admin. This will redirect you to localhost:3000/admin/create-first-user, but show the old UI
