HttpCode for /auth/email/register

[LucaAndrei]

Currently the HttpCode is set to @httpcode(HttpStatus.NO_CONTENT)
Wouldn't it be better to set it to @httpcode(HttpStatus.CREATED) ?

@LucaAndrei reason why we use HttpStatus.NO_CONTENT is we not returned payload for /auth/email/register. Why do we not return the payload: because we handle 2 scenarios:

1. We disallow login users without email confirmation
2. We allow login users without email confirmation

For the first scenario, we shouldn't return any payload about a user within the register flow.

If you have any thoughts about it, please share we consider it.
