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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
