- adds timestamppb.Timestamp to the revocations diff ignore list so
go-cmp does not panic on the unexported fields of the ExpiresAt and
issuedBefore timestamps when validating the router data model
- adds DataState_ServiceConfigs to the identity diff ignore list to
guard the same panic on identity service configs
- applies both ignore-list entries to the RouterDataModelSender diff,
which walks the same nested proto messages and panicked identically
- adds regression tests covering both nested proto-message fields on the
receiver and sender diff paths
