// Create-Organization modal (#35). Platform-admin only (the page is gated; the
// endpoint re-checks). Creates a named org + its first "Default" workspace, owned
// by the creating admin (organizations.owner_user_id is NOT NULL). On success the
// org appears in the switcher, so we reload to refresh it — matching the
// workspace rename/switch flow. opts.onSuccess(result) fires before reload.
