[Bug]: Session is used for stateless routes
Expected behavior
Calling webservice URLs should not cause any problems.
Actual behavior
The call to /__customermanagementframework/webservice/newsletter/get-queue-size causes following error message:
Session was used while the request was declared stateless.
Steps to reproduce
Install the CMF on a Pimcore 11 instance and load into the Pimcore backend. The API call to the newsletter queue check is triggered and throws the exception.
Because the CMF firewall is configured as stateless (https://github.com/pimcore/customer-data-framework/blob/4.x/src/Resources/config/pimcore/config.yml#L26) the routes are expected to not use a session.
See: https://github.com/symfony/symfony/blob/6.4/src/Symfony/Component/HttpKernel/EventListener/AbstractSessionListener.php#L224
