  A generic, white-label sign-in page.

  This live-view can be rendered into your app using the
  `AshAuthentication.Phoenix.Router.sign_in_route/1` macro in your router (or by
  using `Phoenix.LiveView.Controller.live_render/3` directly in your markup).

  This live-view finds all Ash resources with an authentication configuration
  (via `AshAuthentication.authenticated_resources/1`) and renders the
  appropriate UI for their providers using
  `AshAuthentication.Phoenix.Components.SignIn`.
