## Type of Change
<!-- Put an `x` in the boxes that apply -->

- [ ] Bugfix
- [X] New feature
- [ ] Enhancement
- [ ] Refactoring
- [ ] Dependency updates
- [ ] Documentation
- [ ] CI/CD

## Description
New APIs list:
-  orgs for a user.
- merchant accounts for a user in current organisation.
- profile id for a user in current merchant  account.
<!-- Describe your changes in detail -->


### Additional Changes

- [X] This PR modifies the API contract
- [ ] This PR modifies the database schema
- [ ] This PR modifies application configuration/environment variables

<!--
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
Need new list apis for dashboard frontend.
This would allow user to see the list of all the orgs, merchant accounts (in select org) & profile ids (in select merchant account).
<!--
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?
List orgs
```sh
curl --location 'localhost:8080/user/list/org' \
--header 'Authorization: Bearer <JWT>' \
```
response example
```json
[
    {
        "org_id": "org_t4ryeBxwt9RKu8jlsTWq",
        "org_name": "Juspay"
    },
     {
        "org_id": "org_t4ryeBxwt9RKu8jlsTWq2",
        "org_name": "Juspay2"
    }
]
```

List merchants
```sh
curl --location 'localhost:8080/user/list/merchant' \
--header 'Authorization: Bearer <JWT>' \
```
response example
```json
[
    {
        "merchant_id": "juspay",
        "merchant_name": "Juspay"
    },
    {
        "merchant_id": "merchant_1724247367",
        "merchant_name": "Juspay"
    }
]
```

List profile
```sh
curl --location 'localhost:8080/user/list/profile' \
--header 'Authorization: Bearer <JWT>' \
```

response example
```json
[
    {
        "profile_id": "pro_S2E1iXeSzluIrIqH7DNi",
        "profile_name": "default"
    },
    {
        "profile_id": "pro_S2E1iXeSzluIrIqH7DNi2",
        "profile_name": "profile2"
    }
]
```
<!--
Did you write an integration/unit/API test to verify the code changes?
Or did you test this change manually (provide relevant screenshots)?
-->
