Description

Add profile level config to toggle the display for the extended card bin in Payment Response .

Additional Changes

• This PR modifies the API contract
• This PR modifies the database schema
• This PR modifies application configuration/environment variables

Motivation and Context

How did you test it?

• Create a MA and an MCA
• Make a payment with the toggle for that profile_id as false, as it is default
• In the response the card_bin_extended field will be null

• Now set the toggle for that profile_id as true by hitting the following curl:

curl --location 'http://localhost:8080/configs/{profile_id}_enable_extended_card_bin' \
--header 'Content-Type: application/json' \
--header 'Accept: application/json' \
--header 'api-key: {{admin_api_key}}' \
--data '{
    "key":"{profile_id}_enable_extended_card_bin",
    "value":"true"
}'

The config will also be stored in the database, to check you can run the following query

 SELECT * FROM configs WHERE key = '{profile_id}_enable_extended_card_bin';

• Create another payment , now in the Response card_bin_extended field won't be null, as the extended card bin config has been set to true

Checklist
