General: Add course summary to course deletion dialog

[ole-ve]

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 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.
• 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.

Motivation and Context

Implements #9178.

Description

• New endpoint for fetching some course stats
• Display stats on course deletion modal, originated from calling 1 new endpoint and using the data already there

Steps for Testing

1. Log in to Artemis
2. Create a course with an exam, each having one exercise of each type
3. As instructor: Go to course overview -> course name -> delete
4. Verify that all the stats are displayed correctly and look valid

Besides the comments of Patrik code looks good

I reviewed the code and have some change requests

• Please use more specific types
• Please use more descriptive variable names
• Please adjust the german translations
• I think it would be better to only fetch the information when we are actually using the delete functionality, which should be an edge case
