<!--
Provide links to the files with corresponding changes.

Following are the paths where you can find config files:
1. `config`
2. `crates/router/src/configs`
3. `loadtest/config`
-->


## Motivation and Context
<!--
Why is this change required? What problem does it solve?
If it fixes an open issue, please link to the issue here.

If you don't have an issue, we'd recommend starting with one first so the PR
can focus on the implementation (unless it is an obvious bug or documentation fix
that will have little conversation).
-->


## How did you test it?
<!--
Did you write an integration/unit/API test to verify the code changes?
Or did you test this change manually (provide relevant screenshots)?
-->
1. Create a business profile for a merchant (Default one which gets created during merchant account creation works too)
2. Toggle extended card info feature

```
curl --location 'http://localhost:8080/account/:merchant_id/business_profile/:profile_id/toggle_extended_card_info' \
--header 'Content-Type: application/json' \
--header 'Accept: application/json' \
--header 'api-key: test_admin' \
--data '{
    "enabled": true
}'
```

3. For verifying, u could check the db if the feature is toggled using below query
```
SELECT is_extended_card_info_enabled FROM business_profile WHERE profile_id = 'profile_id';
```

## Checklist
<!-- Put an `x` in the boxes that apply -->

- [x] I formatted the code `cargo +nightly fmt --all`
- [x] I addressed lints thrown by `cargo clippy`
- [x] I reviewed the submitted code
- [ ] I added unit tests for my changes where possible
- [ ] I added a [CHANGELOG](/CHANGELOG.md) entry if applicable


Testing:

1. Create a business profile for a merchant (Default one which gets created during merchant account creation works too)
