## 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 #4579. 

## 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)?
-->
As of now, this is only testable in local env. I've removed TOTP from decision manager and directly went to verify email flow.
Previously verify email flow is coming for only verified users, after this change it is coming for only non-verified users.

```
curl --location 'http://localhost:8080/user/from_email' \
--header 'Content-Type: application/json' \
--data '{
    "token": "email token"
}'
```

If the user didn't verify their email, then the `token_type` in the response should be `verify_email`.
```
{
    "token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VyX2lkIjoiMDYxNjE1YjAtZjI5Yi00NWIyLWJmNmItODczNTYyYWU1ODhlIiwicHVycG9zZSI6InRvdHAiLCJvcmlnaW4iOiJtYWdpY19saW5rIiwiZXhwIjoxNzE0ODExOTAwfQ.CDErXJ89a1o3ROyAKvm6TFW1drHDnlcqg43OoBQjY6A",
    "token_type": "verify_email"
}
```
If the user is already verified, then the user should get other flow which is not `verify_email`.
```
{
    "token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VyX2lkIjoiMDYxNjE1YjAtZjI5Yi00NWIyLWJmNmItODczNTYyYWU1ODhlIiwicHVycG9zZSI6InRvdHAiLCJvcmlnaW4iOiJtYWdpY19saW5rIiwiZXhwIjoxNzE0ODExOTAwfQ.CDErXJ89a1o3ROyAKvm6TFW1drHDnlcqg43OoBQjY6A",

}
```
