Issue:
Bug: Modify profile and merchant_connector_account routes to use `ApiKeyAuthWithMerchantIdFromRoute` auth



### Description:
Currently, the following routes use `AdminApiAuthWithMerchantIdFromRoute` for authentication:
- Profile Create, Retrieve, Update
- Merchant Connector Account Create, List, Retrieve, Update

This has to be updated to a more appropriate auth layer: `ApiKeyAuthWithMerchantIdFromRoute`, which validates that the `merchant_id` in the API key matches the one in the route.

## 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).
-->
These routes are profile and merchant-specific and can be accessed using the merchant's API key,
## 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)?
