Fix and require phpstan in gitlab-ci

joelpittet → changed the visibility of the branch 3489747-fix-and-require to hidden.

Working on it.

Hi joelpittet,
I have reviewed the remaining PHPStan errors in detail. Unfortunately, these issues cannot be resolved on our end because they stem from problems within the code itself. Specifically, several functions referenced in the code are missing or undefined, leading to the errors reported by PHPStan.
To address these issues effectively, the missing or undefined functions need to be identified and implemented correctly in the codebase.
Please let me know how you’d like to proceed.
Thanks
