Issue:
Bug: refactor(users): Add V2 user_roles data support



In V2 user_roles data, merchant_id will be null for org level users.

Currently in the BE, we throw 500 if merchant_id is not found in user_role.

So, we should fix this case and get merchant_id from db using org_id if merchant_id is not present in the user_role.

## Type of Change
<!-- Put an `x` in the boxes that apply -->

- [ ] Bugfix
- [ ] New feature
- [ ] Enhancement
- [x] Refactoring
- [ ] Dependency updates
- [ ] Documentation
- [ ] CI/CD

## Description
<!-- Describe your changes in detail -->
- Deprecate all the APIs which are used when `is_token_only` and `groups` query params are false.
- Add logic to get merchant_id from the db if not found in user_role.

### 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
<!--
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).
-->
Closes #5761.
Closes #5762.

## 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)?
-->
From the following endpoints, `token_only` query parameter is removed.
- `/v2/signin`
- `/reset_password`
- `/v2/verify_email`
- `/accept_invite_from_email`
- `/invite/accept` - Post only

All the above APIs will give the following response.
```
{
    "token": "JWT",
    "token_type": "type"
}
```

From the following endpoints, `groups` query parameter is removed.
- `/role` - Get only
- `/role/list`
- `/role/{role_id}` - Get only

They will always respond with groups from now on.

2 new APIs are added.
```
curl --location 'http://localhost:8080/user/signin' \
--header 'Content-Type: application/json' \
--data-raw '{
    "email": "email",
    "password": "password"
}
'
```

```
curl --location 'http://localhost:8080/user/verify_email' \
--header 'Content-Type: application/json' \
--header 'Authorization: ••••••' \
--data '{
    "token": "email token"
}'
```

Both will give the following response if hit correctly.
```
{
    "token": "JWT",
    "token_type": "type"
}
```


## 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

- `/v2/verify_email`
- `/accept_invite_from_email`
- `/invite/accept` - Post only

All the above APIs will give the following response.
```
{
    "token": "JWT",
    "token_type": "type"
}

--header 'Content-Type: application/json' \
--header 'Authorization: ••••••' \

}'
```

Both will give the following response if hit correctly.
```
