Add button to delete all WireGuard configs (#2595)

Add a new button in the toggle buttons to delete all the added WireGuard
config options at once. Show a dialog box before deleting which
indicates that it's irreversible (unless they still have access to the
wireguard files).
Add Malayalam translation for the dialog.
