feat: port secretaries tab from tauri to admin my-secretaries page

- Redesign MySecretariesPage pixel-perfect to clinic-pro-tauri (active/previous
  tabs, desktop table, mobile cards, add/edit/view modal with permission
  accordions, deactivate confirm)
- Permission sections based on existing admin pages (appointments, patients,
  payments, insurances, addresses, clinic_info)
- Extend DoctorSecretary with national_code + address columns (+migration);
  wire create/update in SecretaryController; add patients/payments to
  DEFAULT_PERMISSIONS
- Extend Secretary/SecretaryPermissions types; update admin SecretariesPage
- Backend + frontend tests; update docs/api/secretary.md
