Deleting the Service between test runs causes a FailedToUpdateEndpoint
error (UID precondition failure) when the old Endpoints are garbage
collected and the new Service tries to create fresh Endpoints. This
leaves the service unreachable by DNS (ERR_NAME_NOT_RESOLVED).
Fix: stop deleting the Service. kubectl apply upserts it in-place,
so the existing Endpoints object persists. The new pod IP is added
automatically when the fresh Deployment pod becomes ready.
Closes PRI-609
