feat(desktop-client/wangyihao): harden token capture and draft submit flow

Inject the YiDun guardian client to obtain ursToken without relying on
window.neg, fetch the publish detail (wemediaId/onlineState/...) before
saving drafts so 100002 "参数错误" stops blocking submit, downgrade
markdown tables to paragraph rows like Baijiahao, and surface friendlier
errors for token, draft and publish-click failures.
