fix: review 'Archive' button was mislabeled delete, zero confirmation

The bulk button read 'Archive' but called applyBulkDelete() ->
gateway.deleteReview() - a real hard delete, and reviews have no
archived status in the model at all, so 'archive' was never a real
concept here. Relabeled to 'Delete' and added an app-confirm-dialog
gate, same pattern as products/categories/orders.
