Feature request: Add delete confirmation dialog to file manager (#344)

* Feature request: Add delete confirmation dialog to file manager

- Added confirmation dialog before deleting files/folders
- Users must confirm deletion with a warning message
- Works for both Delete key and right-click delete
- Shows different messages for single file, folder, or multiple items
- Includes permanent deletion warning
- Follows existing design patterns using confirmWithToast

* 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.

* feat: Add Chinese translations for delete confirmation messages
