CC-38848 Drain publish queue while waiting for deleted attachments to clear

[stereomon]

Summary

product-attachment-storefront.cy.ts "…cannot see attachments after they are deleted in backoffice" flakes run-to-run on master compat CI. Root cause is test-infra, not product code: the delete's publish→sync is a multi-stage queue chain, and reloadUntilGone reloaded the PDP but never re-drained the queue between reloads (unlike reloadUntilFound), so a lagging sync message never landed and the list never disappeared ("exhausted retries").

Fix: reloadUntilGone now takes a commands arg (mirroring reloadUntilFound) and re-runs the queue worker on every reload, so the wait keeps draining until storage actually reflects the delete.

Test plan

• tsc --noEmit + Prettier green locally.
• Cypress CI on this branch: the attachment-storefront spec passes without exhausting retries.
