For developers: what the fix changed

This release carries 2 security fixes. The summary below is for SA-CONTRIB-2026-125, the most serious of them.

The fix removes the insecure passing of error messages via the `q` URL parameter and its subsequent unescaped output in `otp_verification_form_user_register_form_alter` within `otp_verification.module`. It also updates message rendering in `src/Form/MiniorangeValidateUser.php` to use proper placeholders like `@msg` in the `t()` function and escapes the `tx_id` parameter to prevent XSS.

Also in this release The release also includes bug fixes related to session handling, cookie management, and redirect logic.
