Add ai_platforms table + shared catalog (yuanbao/kimi/wenxin/deepseek/doubao/qwen),
drop FKs from platform_accounts and desktop_tasks to media_platforms, and wire
target_account_id + platform into DesktopTaskEvent so the desktop runtime no
longer has to infer them from local state. Desktop client gains generic AI page
detection for binding, drops stale-business-date monitor tasks at the edge, and
refactors AccountsView/AiPlatformsView around the shared catalog. Admin tracking
view surfaces per-platform sampling status cards.

Treat ambiguous terminal states as failures end-to-end: server
normalizes unknown desktop task completions and views to failed, drops
the pending_review aggregate branch, and remaps pending_review to
failed in publish record conversion. admin-web removes the
pending_review status option from article list filters, pushes
pending_review through the failed tone, and folds lingering
publishing/pending entries under the publishing bucket. desktop-client
relabels unknown as 发送失败 in PublishManagement/TasksView, rewrites
the scaffold adapter result to a proper failed error envelope, and
sanitises legacy scaffold-only error messages to a user-friendly note.
