fix: Unhandled IOException in DeleteSelectedFiles crashing the app

[blackyale]

Fixes a crash when trying to delete files that are locked by another process (e.g. OneDrive sync, antivirus). Previously, an unhandled IOException would kill the app. Now the deletion loop catches the exception, logs a warning, and keeps going so the rest of the selected files still get deleted and the file list refreshes properly.

I'm sorry about the delay 🌷 Thank you for your contribution. I'm a bit curious how the code crashes the app instead of throwing an Exception. Do you have any idea?

I have one revision request: can you simplify System.IO.IOException as simply IOException?

[blackyale]

It is an unhandled exception that is elevated to the application invoking this method. I found it happened only to one user among hundreds but still worth handling it I'd say. I'll add the revision remark you did, thanks a lot for your time and such a great tool you have created.

Update IOException remark

I've changed the warning to be an error and provided the file's path in the error log. Thank you for your contribution!

Wow I've managed to create a compiler error. But I'll fix it promptly 🙈
