Development: Prevent unnecessary requests to the server for IRIS availability in the exercise view

[Hialus]

Checklist

General

• I tested all changes and their related features with all corresponding user types on a test server.
• This is a small issue that I tested locally and was confirmed by another developer 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

• 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.
• I documented the TypeScript code using JSDoc style.

Motivation and Context

We had quite a bit of unwanted request spam in the student exercise view.

Description

This as caused by some missing unsubscribes, which I added in this PR.

Steps for Testing

Prerequisites:

• 1 Student
• Multiple Programming exercises in one course

1. Log in to Artemis
2. Go to the course student exercise view
3. Switch between the exercises
4. In the network tab there should not be an every increasing spam of requests for the same few URLs

The recent changes focus on enhancing subscription management in two components. These updates aim to ensure proper subscription initialization and cleanup to prevent memory leaks and maintain code cleanliness in the chatbot-button.component and course-exercise-details.component.

Changes

File Path	Changes

.../overview/exercise-details/course-exercise-details.component.ts	Improved subscription handling and initialized irisSettings to undefined.

Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
