feat(publish-dedup): disable already-published accounts and rework retry UX

In the admin publish modal, fetch the article's publish records, disable
accounts that already succeeded for the same article/platform, label
queued/publishing accounts inline, and route the success notification by
created vs existing task counts (with a dedicated warning for the
`desktop_publish_duplicate` server error).

Replace the "再次发送" mutation/popconfirm on both admin and desktop publish
management views with a "重新创建发布任务" action that calls the same Create
endpoint, only enables on failed/aborted/unknown rows, and reports created
vs existing task counts (with a tailored warning for `unknown` results
that may have already succeeded).
