- Implemented `ForgotPasswordViewModel`, `ResetPasswordViewModel`, and `VerifyOtpViewModel` for handling respective functionalities. - Created provider functions for lazy loading of these view models in the app. - Updated routing to utilize the new providers for managing state in the forgot password flow. - Refactored UI components to integrate with the new view models, ensuring proper state management and user feedback during operations.
