Files view node order changes after startup

### Apache NetBeans version

Apache NetBeans 21

### What happened

Opening a Maven multi module project displays the nodes in alphabetic order in the Projects and Files views. After restarting the IDE however, after the IDE is done "Opening Projects", the order changes in the Files view for some reason. Closing and reopening the project fixes the issue, but doing this every time is annoying because e.g. the main project information is lost.

I only use Maven projects, so I'm not sure if this is a Maven project issue or present with other types of projects.

Here is a video demonstrating the issue:

### Language / Project Type / NetBeans Component

Projects/Files view in NetBeans IDE

### How to reproduce

Create new or open existing Maven project with multiple modules and restart NetBeans IDE.

### Did this work correctly in an earlier version?

No / Don't know

### Operating System

Windows 11

### JDK

21.0.2; OpenJDK 64-Bit Server VM 21.0.2+13-LTS

### Apache NetBeans packaging

### Anything else

_No response_

### Are you willing to submit a pull request?

No

Start by reproducing the ordering change with a multi-module Maven project on Windows 11, following the issue's restart sequence. Trace the Projects/Files view startup and project-opening flow; done means node order remains stable after restarting NetBeans without closing and reopening the project.
