test(sweep): add capture surfaces for the Wave-1 standalone modals

Register sweep surfaces so the redesigned Wave-1 modals get captured for visual
review: modal-qr-popup, modal-request-payment, modal-validate-address,
modal-address-label, modal-daemon-prompt, and modal-antivirus (the last renders
only on Windows, where its #ifdef body compiles). Each is driven through the
dialog's public show()/flag; teardown closes it. Adds a static hide() to
RequestPaymentDialog / ValidateAddressDialog / AddressLabelDialog for clean sweep
teardown (they had no public close). The contact add/edit and explorer block-detail
modals are tab-embedded and not yet surfaced.
