Pull Request Overview

This PR implements SMS OTP MFA (Multi-Factor Authentication) and JIT (Just-In-Time) support for native authentication, building on the existing email OTP MFA implementation. The changes make verification contact a mandatory field for SMS authentication methods and update the API to handle SMS-specific authentication flows.

Key changes include:

• Removal of selection-based MFA flows in favor of direct auth method specification
• Addition of SMS channel support with mandatory verification contact validation
• Simplification of MFA state machine by removing getAuthMethods() functionality
• Enhanced JIT states to support both email and SMS verification contacts
