- Add missing .confirm-dialog.active { display: flex; opacity: 1 } CSS rule.
The confirm dialog was created with display:none and the .active class
was added, but no CSS rule changed it to visible — so the user never
saw the confirmation prompt and delete appeared to do nothing.
- Capture file/folder target before closeContextMenu in delete handlers
to prevent null reference race condition (same as rename/share fix).
