/**
 * Settings sub-navigation for the subscription page — item list and order copied
 * verbatim from clinic-pro-tauri's `PurchaseSubscription.jsx` navItems, minus
 * "مدیریت پزشک" (that lives in the main nav / doctor profile, not here). Shown
 * ungated to mirror the tauri source. Each entry maps to a real admin route; the
 * "تنظیمات" (security) section has no doctor/clinic route yet → disabled.
 *
 * This list is intentionally separate from SETTINGS_MENU (SettingsLayout) so the
 * other settings pages are not affected.
