refactor(router): changed payment method token TTL to api contract based config from const value

[sahkal]

Type of Change

• Bugfix
• New feature

Description

Currently the payment method token TLL calculation was done based on const::TOKEN_TTL - payment_intent.created_at

where TOKEN_TTL was 15mins, but as we have a new contract called session_expiry we can make our payment live for longer time constraint than just 15mins,

due to this, the value const::TOKEN_TTL - payment_intent.created_at might go negative if the payment is done after 15mins. Which causes negative value at redis.

To solve, This problem we have used intent_fulfillment_time in business profile which is set by the merchant.

max value of intent_fulfillment_time can be 30mins and min can be 1min

How did you test it?

[Scenario 1] : Create a new business account
Create a merchant -> Create business profile with intent_fulfillment_time as 60s -> do payment connector step -> Create api key ->

Business Create

curl --location 'http://localhost:8080/account/merchant_1719312571/business_profile' \
--header 'Content-Type: application/json' \
--header 'api-key: test_admin' \
--data '{
  "profile_name": "fooddqw",
  "intent_fulfillment_time":60
}'

Do payment create with payment link

curl --location 'http://localhost:8080/payments' \
--header 'Content-Type: application/json' \
--header 'Accept: application/json' \
--header 'api-key: dev_Ccb0N9Nd43rBhCANbXit86h820vVpcXkexpgbAw5efxjwiUC6UYiTeOtW446kkpa' \
--data-raw '
