Log and track successful and failed credit card verification events

What does this MR do and why?

Implement Log when credit card is rejected because it was previously used for verification by a user that has been banned as part of CC/Phone Verification should fail for medium/high risk users that use a cc or phone number that has previously been banned.

For monitoring/debugging and analysis purposes, this MR implements logging and event tracking for the following events during identity verification:

1. When the user successfully completes the credit card verification step–after BE checks that no banned user has previously used the provided credit card details
2. When the user fails to complete the credit card verification step–a banned user has previously used the provided credit card details
