Adds confirmation for deletion of items including folders

Updates the file deletion confirmation logic to distinguish between
deleting multiple items with or without folders. Introduces a new
translation string for a clearer user prompt when folders and their
contents are included in the deletion.

Improves clarity and reduces user error when performing bulk deletions.
