title: 'rpc server: fix deny unsafe on RpcMethods::Auto'

Close #5677

I made a nit when I moved this code: https://github.com/paritytech/polkadot-sdk/blob/v1.14.0-rc1/substrate/client/service/src/lib.rs#L379-#L385 in https://github.com/paritytech/polkadot-sdk/pull/4792

Thus:
- (ip.is_loopback(), RpcMethods::Auto) -> allow unsafe
- (!ip.is_loopback(), RpcMethods::Auto) -> deny unsafe
