Pull Request Template

Description

I discovered Sequelize would crash on MariaDB when core/db/migrations/20250118235051-change-grading-attendance.js attempted to delete QuestionInLecture.order. There was a key constraining QuestionInLecture.order and QuestionInLecture.lectureId, that in turn was constrained to a foreign key binding QuestionInLecture.lectureId and Lecture.id. I made the script not delete QuestionInLecture.order until both keys were deleted too.

Fixes #332

Additional Information

Testing on a MySQL-based system is needed.
