refactor(services): merge insurance coverage into the service edit modal

- extract ContractCard + contracts list from ServiceInsuranceModal into a
  new inline ServiceInsuranceSection (no dialog wrapper; buttons type=button
  so they don't submit the parent service form)
- ClinicServicesPage: drop the separate 'پوشش بیمه' menu action and its
  standalone modal; render coverage inline under the service fields in the
  edit modal (edit only — needs the item uuid; create shows a hint)
- delete now-unused ServiceInsuranceModal.tsx
- fix undefined --primary-subtle token → --primary-soft
- test: coverage renders inline inside the service edit modal
