refactor(sidebar): single 'تنظیمات' entry, move settings items out of main nav

For the doctor and clinic roles, collapse the subscription section into one
'تنظیمات' item (Cog icon) pointing at /admin/subscription, matching the tauri
main sidebar. Remove the items that now live in the in-page settings submenu
(insurance-pricing, clinic-services, sms-wallet) from the main nav so they are
not duplicated. Secretary (no settings page) is unchanged.
