feat(publishing): incremental queue item list (#4787)

[natechadwick-intsof]

Summary

PublishingShell Incremental preview lists queued items as rows (content id and title or name) instead of a count. An empty queue stays an empty state with no rows. A failed list request shows an error and does not invent rows.

Parent: #4531. Slice: #4787.

Operator: Grok: night-issue-prs (model grok-4.7)

Test plan

• Vitest incrementalQueue id/label helpers and SiteWorkspace rows, empty state, and load failure
• Playwright tests/publishing-incremental-queue-list.spec.js on H2 QA (3 passed): rows, empty, load failure; console-clean=yes on success paths
• Human spot-check on a site that already has a real incremental queue (Playwright proved the list against a stubbed queue payload on a live H2 site workspace)

Product documentation

• Updated product-docs/8.2/admin/publishing.md (incremental preview rows)
