test(document): run OCR-status page tests as a writer (#697)

The OCR status check is now gated behind canWrite (readers do no write-path
work), so the two OCR-status page tests must render as a writer — OCR is a
writer action. Without canWrite the status check never fires and the "OCR
läuft" spinner never mounts. Fixes the CI regression introduced by confining
read-only users to the read view.
