test(e2e): provide documents on the live self-service tab after the zaak opens (refs #102)

The process only parks at WachtOpDocumenten once the OpenZaak worker has opened the
zaak, so providing documents immediately after submit raced the wait and no-op'd.
Check the openbaar INGEDIEND row on a second page (proving the zaak is open, hence
the process is at the wait) while the self-service tab keeps its submitted state,
then provide documents there — unblocking the werkbak.
