[Enhancement] Use clientDecode for consuming message directly

[cserwen]

Before Creating the Enhancement Request

• I have confirmed that this should be classified as an enhancement rather than a bug/feature.

Summary

Currently, when users push messages directly from the console, messageExt.getMsgId returns offsetMsgID instead of the uniqId generated by the client, which may cause confusion for users.

Motivation

In order to make the msgID seen by production and consumption consistent

Describe the Solution You'd Like

Use clientDecode method instead of decode，

Describe Alternatives You've Considered

No
