Add MFA support to login response and related structures

- Updated the LoginResponse structure to include MFAEnabled status, reflecting the user's MFA configuration.
- Modified the authback function in oauth.go to return the MFAEnabled status in the response.
- Introduced a utility function to convert various types to boolean for determining MFA status from user data.
