Services are referenced by appointments, sessions, invoices and payment history,
so deleting one orphans/corrupts those records (deleting a section cascaded to
its services too). Make deletion impossible:
- Backend: DELETE /service-item/{uuid} and DELETE /service-section/{uuid} now
always return 409 (ERR_SERVICE_ITEM_IN_USE) with a message pointing to
deactivate; no rows are touched. Deactivate stays via PATCH active=false.
- Frontend: removed the section delete button, its confirm dialog, the delete
mutation, and the now-unused delete state/flag/icon from ClinicServicesPage.
Section and item deactivate toggles are unchanged.
Tests: ServiceItemDeleteCleanupTest rewritten — delete of item and section both
rejected (409) and the row survives. docs/api/clinic-services.md updated.

Tariff and TenantServiceCoverage reference a service item by a raw int (no FK),
so deleting an item orphaned its tariffs and tenant-coverage config. Delete them
in deleteItem() before removing the item. (The in-use FK guard for invoice/claim
usage is preserved.)
Remaining M20 refs (ClinicStaff/SmsWallet/DoctorAddress.clinicId/Claim.insurance_id
on rare owner deletions) are accepted as harmless unreferenced rows; SmsWallet is
intentionally retained as a financial record. Documented in docs/audit-backlog.md.
Regression: tests/ClinicService/ServiceItemDeleteCleanupTest.
