Iris: Enable Iris for exercises based on their categories

[Hialus]

Checklist

General

• I tested all changes and their related features with all corresponding user types on a test server.
• Language: I followed the guidelines for inclusive, diversity-sensitive, and appreciative language.
• I chose a title conforming to the naming conventions for pull requests.

Server

• Important: I implemented the changes with a very good performance and prevented too many (unnecessary) and too complex database calls.
• I strictly followed the principle of data economy for all database calls.
• I strictly followed the server coding and design guidelines.
• I added multiple integration tests (Spring) related to the features (with a high test coverage).
• I added pre-authorization annotations according to the guidelines and checked the course groups for all new REST Calls (security).
• I documented the Java code using JavaDoc style.

Client

• Important: I implemented the changes with a very good performance, prevented too many (unnecessary) REST calls and made sure the UI is responsive, even with large data (e.g. using paging).
• I strictly followed the principle of data economy for all client-server REST calls.
• I strictly followed the client coding and design guidelines.
• Following the theming guidelines, I specified colors only in the theming variable files and checked that the changes look consistent in both the light and the dark theme.
• I added multiple integration tests (Jest) related to the features (with a high test coverage), while following the test guidelines.
• I documented the TypeScript code using JSDoc style.
• I added multiple screenshots/screencasts of my UI changes.
• I translated all newly inserted strings into English and German.

Changes affecting Programming Exercises

• High priority: I tested all changes and their related features with all corresponding user types on a test server configured with the integrated lifecycle setup (LocalVC and LocalCI).
• I tested all changes and their related features with all corresponding user types on a test server configured with Gitlab and Jenkins.

Motivation and Context

Currently, instructors have to enable Iris for every individual exercise, which is annoying and easy to miss for one exercise.
A better option would be to enable Iris automatically for exercises based on some criteria or to switch between opt-in and opt-out for exercises.
After talking with @bassner and @krusche, we decided that the way to go is to enable Iris automatically based on the categories of exercises.

Description

• Added a settings option in the course setting to select categories, for which Iris will be activated
• Whenever the course settings categories are updated, the exercises' Iris-enabled states are synched
• Whenever an exercise's categories change, the Iris-enabled state is synched
• Also fixed a bug that prevented Text exercises with Iris Settings to be deleted

Steps for Testing

Prerequisites:

• 1 Instructor
• 1 Programming Exercise
• 1 Text exercise
• 1 Course with Iris enabled (needs an admin account)

1. Log in to Artemis
2. Navigate to Course Administration
3. Add some categories to the exercises
4. Open the Iris settings of the course
5. Select some categories
6. Check the exercises Iris settings
   a. If the exercise has a category that is included in the course Iris settings, Iris is enabled
   b. If the exercise has no category that is in the course Iris settings, Iris is disabled (unless manually enabled)
7. Change the categories in either the course Iris settings or the exercise
8. Iris will be correctly enabled/disabled for the exercises

Review Progress

Performance Review

• I (as a reviewer) confirm that the client changes (in particular related to REST calls and UI responsiveness) are implemented with a very good performance even for very large courses with more than 2000 students.
• I (as a reviewer) confirm that the server changes (in particular related to database calls) are implemented with a very good performance even for very large courses with more than 2000 students.
