fix(router): fixed integrity check failures in case of 3ds flow in sync flow

[sahkal]

Type of Change

• Bugfix

Description

we have implemented integrity checks for stripe, we have implemented integrity in authorise, sync, capture and refund, refund sync

but, where in sync flow we check amount, currency and amount_captured.

the bug is in 3ds flow, where after the transaction is completed we do a sync with the connector, but our trackers are not updated at this point.

In 3ds transaction we rely on connector sync to update our trackers, since integrity checks happens with data before post update trackers we were comparing MinorUnit(0) our amount captured to Some(MinorUnit(x)) amount received by the connector.

due, to this there was a data mismatch issue, which led to integrity check failure.

How did you test it?
