In the other SDKs we call this TokenAmount as the type also appears in e.g. events/returnValues.

Suggested change

	public class TokenOperationAmount {
	public class TokenAmount {

Here it is intentionally different – the GRPC model has no unsigned number wrapping, and it is not CBOR-serializable.

Looks good to me. Just a couple of issues where preferred serialization should be used for integers.
