General: Fix exercise archival for courses and exams

[julian-christl]

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) database calls.
• I added multiple integration tests (Spring) related to the features (with a high test coverage).
• I strictly followed the server coding and design guidelines.

Motivation and Context

Fixes #8521

Description

• I ensured that the exercise detail configurations get loaded on export to prevent the initialization error.
• I fixed some minor code issues along the way.
• I added the team config to the export for consistency.
• I added two tests covering the issue, I confirmed that they fail on develop.
• While fixing tests, I had to fix the issue that the plagiarism detection config wasn't transferred on import

⚠️ Unable to deploy to test servers ⚠️

The docker build needs to run through before deploying.

Tested the exam mode on ts2, exporting the finished exam with partitipations in all exercises worked without any problems. I was able to download the archive 👍
