<!--
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?

- Create a MA
- Create two MCA , one with the `connector_type : "payment_processor"` other with the connector type as `payout_processor`

- Create a payment
- Do a list of Pms for the Merchant Account, BOA would not be here as its connector_type is `payout_processor`, cause here only the PMs with `payment_processor` would get listed
