Admidio's CSRF in registration `send_login` mode resets arbitrary user passwords

Description

Admidio is an open-source user management solution. `modules/registration.php` mode `send_login` regenerates a random password for `user_uuid_assigned`, stores its bcrypt hash in `adm_users.usr_password`, and emails the cleartext to that user. Every other state-changing mode in the same file (`assign_member`, `assign_user`, `delete_user`, `create_user`) calls `SecurityUtils::validateCsrfToken($_POST['adm_csrf_token'])` first; the `send_login` branch does not. Prior to version 5.0.10, page visited by a registration-administrator can issue the request as a top-level navigation, the browser sends the admin's `SameSite=Lax` cookies, and the server resets the chosen user's password without any further interaction from the admin. Version 5.0.10 fixes the issue.
