Description

This PR introduces a new "Load Project" feature, including UI changes and backend logic.
Changes were made to four files to implement this feature:

1. projectLoadUI.js:

   • Added two functions:
     • loadUserProjects(): Handles the logic for loading user projects.
     • ShowProjectLoader(title, getChoices): Displays a modal for selecting a project.

2. editorMain.js:

   • Updated setupIDEButtonEvents() to add:
     • A new "Load Project" button and its associated event handler.

3. IDEStartupMain.js:

   • Added LoadUserProjectQueue to manage project loading operations during IDE startup.

4. index.html:

   • Added the following snippet to integrate the "Load Project" button into the UI:

     <li><button id="LoadProject">Load Project</button></li>

However, clicking the "Load Project" button or the "Load Demo" button does not yet trigger the expected behavior. The changes have been marked with !!! in the comments to help reviewers quickly locate the relevant sections. Further debugging and review are required to fix this issue.
