Build/Test Tools: Cover moving selected posts to Trash in bulk.

Add a browser test that selects two published posts and moves them to Trash through the bulk-action form. Verify both saved statuses become `trash` while an unselected control remains visible and published.

Create fixtures through REST and delete only those posts during cleanup.
