feat(settings): role-aware settings menu

Add an optional `roles` filter to the settings menu and hide items that don't
apply to the current user's role, so a doctor no longer sees "مدیریت مطب"
(clinic-only) and a clinic no longer sees "مدیریت پزشک" / "مدیریت نوبت دهی"
(doctor-only) — avoiding menu entries that just redirect. Both the desktop
shell (SettingsLayout) and the mobile list (SettingsMenuPage) filter via the
shared `menuForRole` helper.
