chore(phpstan): address unknown classes for PHPStan analysis

This commit addresses the issue of PHPStan not recognizing certain classes for type validation
within our PHP codebase. This is done by adding these classes to the PHPStan configuration as
ignored errors. This ensures accuracy in our static analysis for errors and warnings. Key classes
such as QUI\\ERP\\Process, QUI\\ERP\\Accounting\\Calc and QUI\\ERP\\Accounting\\ArticleList have
been catered to.
