Folder drop ignores parallel processing setting

[brandishwar]

Lychee version

7.8.3

Did you check the latest Lychee version?

Yes, I did

Which PHP version are you using?

PHP 8.5

Detailed description of the problem

Images are no longer processed in parallel when dropping a folder onto Lychee. However the images are processed in parallel when selecting multiple images and dropping that group into a gallery. This appears to be a bug introduced with the latest version as I did not observe this bug until pulling the latest update today.

Lychee.drag.drop.bug.mp4

Steps to reproduce the issue

1. Navigate to the Lychee gallery page.
2. Drop folder with photos onto the page. Observe that the images are processed individually, not parallel.
