This commit enhances the cookie handling logic by providing detailed comments on the SameSite attribute options and their implications for security. It sets the default SameSite value to 'none' to allow iframe embedding while ensuring that Secure is true when SameSite is 'none'. Additionally, it adds a warning for cases where SameSite is 'none' but Secure is false, improving the overall security posture of cookie management.
