## Summary by CodeRabbit
* **Bug Fixes**
* Sign-in, sign-up, MFA, SSO, reset password, and forgot password forms
now explicitly submit using **POST** for more consistent authentication
behavior.
* **Style**
* Reformatted authentication form markup (e.g., multiline JSX
attributes) to improve readability and maintainability.
