feat(auth): hide password login when disable_password_auth is set (#438) (#121)

Thank yWhen the backend resource endpoint reports disable_password_auth, the login
view hides the username/password form, the 'or' divider and the 'Create new
account' button, leaving only the configured SSO button — so SSO-only
instances present a clean login.

Auth options render only once the resource query has settled, so the password
form never flashes before being hidden (no FOUC) on SSO-only instances.

Also drops a dead setUserProfile(user) call in the post-auth effect (the
symbol was removed earlier, leaving a no-undef that broke lint on this file);
the profile now comes from useUserProfile().
