feat(desktop): drop parked review flow, add publish management

SaaS 侧人工审核后才创建 publish job，desktop 不再做二次审核：移除
manual/waiting_user/parked/from_parked 状态机与 LeaseFromParked 查询，
desktop client 只执行发布并新增"发布管理"页（待发布队列 / 历史 / 再次
发送）。同时抽离 @geo/publisher-platforms 共享适配器包、新增 Redis-based
desktop_presence 与 publish_record_support，刷新 admin-web 发布弹窗与
媒体库；plan A / spec 文档同步口径。
