Exam mode: Improve usability and readability of results summary

[florian-glombik]

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.

Client

• I followed the coding and design guidelines.
  Did not find a better alternative to "Prüfungsteilnehmer:in"
• 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, wherever the method name is not self-explanatory.
• I added multiple screenshots/screencasts of my UI changes.
• I translated all newly inserted strings into English and German.

Motivation and Context

Resolves #7203

Description

Exam Mode Testing

Prerequisites:

• 1 Instructor
• 1 Students (You can also view the Student Submission as instructor, then you do not need to use a student)
• 1 Exam with all exercise types (Programming, Quiz, Modelling, FileUpload, Text)

1. student: participate in the exam, see that the confirmation screen appearance has changed
2. student: view the ungraded summary directly after participating in an exam
3. instructor: start and participate in a test run exam -> the start page and summary are relevant
4. student: view the summary with a graded participation
   a) the general information should be easier to understand
   b) the result overview should link to the exercises (onClick -> scrolling to exercise)
   c) the grading keys should be collapsable (and no links to other pages)
   d) readable in darkmode
   e) the grading scale button is not visible if no grading scale exists
   d) the bonus grading scale button is not visible of no bonus grading scale exists
5. instructor: the grading key table is still displayed properly when accessed as page

Tested on TS2, all looks good now. Thanks for implementing the changes!

The misleading description within the bonus grading key table is known and will be addressed in a follow-up PR - this issue does already exist on develop.

[Strohgelaender]

re-tested on TS2, I did not find any issues and the new look is quite improved.

In a followup we might improve this tooltip, I think it should be much simpler for students (e.g. just ' You did not participate in this course').

code looks good to me as well.

[MaximilianAnzinger]

I've some suggestions.

Retested on TS2,

looks really nice as long as the student name or course name is not very long
