Bug Description

Dropping files from the desktop onto a breadcrumb moves the selected items into that folder. Cause: packages/design-system/src/components/OcBreadcrumb/OcBreadcrumb.vue:249-258 emits itemDroppedBreadcrumb for any drop, including OS files; GenericSpace.vue:443-507 then moves the selection.

Reproduction Steps

1. Open a subfolder and select some files.
2. Drag a file from the desktop onto a parent breadcrumb and drop it.

Expected Outcome

Only the dropped file is uploaded; nothing is moved.

Actual Outcome

The selected files are moved into the breadcrumb folder without confirmation, and the dropped file is uploaded into the current folder.
