[BUGFIX] Properly add columns for uploaded files

A couple of patches changed the amount of columns,
shown in the filelist module listing. For example, since
column selector component. Also multi record selection,
introduced in #94906, adds an additional column,
providing the checkbox.

This patch therefore adjusts the DragUploader component
to take this into account while dynamically adding rows for
uploaded files.
