Files/tabs sort inconsistency

### Apache NetBeans version

Apache NetBeans 15

### What happened

The files in the Projects tab are sorted by ASCII (as far as I can tell). The open tabs within the editor are sorted alphabetically. Why is this inconsistent? IMO the sort sequence should be an option in the Options window (and should default to alphabetical NOT ASCII) so that the dev can choose how to sort globally.

Some will say this is a personal preference ... then make it a preference ... at least be consistent.

### How to reproduce

Open a project with files that are named some with uppercase and some with lowercase within the same folder. As for the Editor, open files with the same criteria as above.

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

No / Don't know

### Operating System

Windows 10

### JDK

Irrelevant

### Apache NetBeans packaging

Apache NetBeans binary zip

### Anything else

_No response_

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

No

### Code of Conduct

Yes

Reproduce the issue in Apache NetBeans 15 by comparing file ordering in the Projects tab with open-tab ordering for mixed-case names on Windows 10. Trace where each view determines its sort sequence, then verify that the behavior is consistent and that the requested sorting preference is available in the Options window.
