Assessment criteria order changes randomly after saving ([team] programming exercises)

[rabeatwork]

Describe the bug

When editing the assessment criteria of a programming exercise, the order of criteria changes after saving. I enter the assessment criteria in a specific order, but after clicking 'Save', some items are rearranged seemingly at random. This affects both the order of categories and the order of individual assessment criteria within categories.

I noticed this especially when creating a larger number of assessment criteria. The reordering does not always happen in the same way, which makes it feel unpredictable.

To Reproduce

1. Open an existing programming exercise (or create a new one).
2. Edit the exercise.
3. Add or edit the assessment criteria (including categories).
4. Click Save.
5. Go to Assessment Dashboard
6. Observe that categories and/or criteria are rearranged.

Expected behavior

Assessment criteria (including categories and items within categories) should be rendered and stored in the exact order in which they were entered in the exercise editor.
