Item 5 of #279 required bringing the image-search auto-link annotation into the purchase-facing views, display-only, without gating anything. - BatchPreviewItem and AdminTaskItem now carry imageSearchLinked, sourced read-only from shopee_product.image_search_linked (already loaded in the batch preview dataset; bulk-loaded for the task list/detail views). - Batch purchase preview dialog and purchase task list/detail now show a "图搜未核" tag plus a restrained summary hint when applicable. - Does not touch Eligible/ReasonCode/Reason/NextAction or the #283 mappingTargetsValid gate; regression test confirms an ineligible row's outcome is unchanged when imageSearchLinked is true.
