The status of a transaction and mandate needs to be consumed separately as they are not co-related. Yes, Transaction can be CHARGED but mandate status can be still CREATED. CREATED means that it is in a pending state. Also note that a failed transaction will not have an ACTIVE mandate. It might also fail or stay in created state.

NO, CHARGED transactions can have different mandate status.
This won't be a right implementation. Please consume the mandate status from the mandate block in the webhook and order status. Order status should be the final source of truth.
