Exam mode: Reduce width of sidebar

[rabeatwork]

Checklist

General

• This is a small issue that I tested locally and was confirmed by another developer on a test server.
• 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 added multiple screenshots/screencasts of my UI changes.

Motivation and Context

We aim to provide students with more horizontal space, particularly when they use split-screen during an exam.

Description

This PR removes the padding and the extra background of the sidebar.

Prerequisites:

• 1 Students

By reducing the sizes of both open and closed sidebar states and improving transition effects, the design aims to create a more user-friendly experience. These modifications enhance visual hierarchy and accessibility, allowing for smoother interactions and improved aesthetics.

  • @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 gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.

Code and Screenshots look good to me

[coolchock]

tested on ts5, looks good 👍

[edkaya]

Code looks good to me. Tested on TS5. Extra padding and background in sidebar is removed as described. However, I found the following minor issues:

• if we have more than 10 questions in an exam, overview icon can not be seen fully. Besides, is it intended to place the collapse icon on the right when the sidebar is collapsed? (See screenshot 1)
• If we shrink the window to the left, there is a horizontal and vertical scrollbar. Vertical scrollbar also blocks the status icons of questions. I think we also need to remove the horizontal scrollbar and display question and status icon next to each other in this edge case. (See screen record)
