Missing timestamp in GetTxsEvent response

[ted341]

Summary of Bug

While using the new API endpoint /cosmos/tx/v1beta1/txs to query historical transactions, I realized that the timestamp returned an empty string, which I believe the field was not filled in with data.

Version

v0.41.3

Steps to Reproduce

https://BASE_URL/cosmos/tx/v1beta1/txs?events=message.action=send&events=transfer.sender=ANY_ADDRESS&pagination.limit=1

Might be tackled in one go with #8681 (comment). It seems that we forgot a bunch of fields when converting to Tm's TxResult to SDK's TxResponse
