fix: consider logout for GuestOrderUser -> destroys session

See merge request !32

Multiple updates have been made updating specific software versions and modifying code for email
verification. We updated the phpstan version in phars.xml as well as added a new dependency in
composer.json. We also refactored the EmailVerification class and the associated
sendEmailVerification function. Changes include:

1. Modification of the phars.xml file to use a more recent version of phpstan.
2. Addition of a new software dependency to composer.json.
3. Switching from using the deprecated AbstractVerification class to the LinkVerification class.
4. Adjustments to method signatures and error messaging in EmailVerification class.
5. Changes to the sendEmailVerification function in the GuestOrder class to accommodate the updated
LinkVerification class.

This commit introduces a new feature to the GuestOrderUser class under `src/QUI/ERP/Order/Guest/`.
A logout method is added, which calls the `destroy` function from the `QUI` session, allowing a
guest user to log out.
