feat(desktop): add Wenxin monitoring adapter and surface platform risk control

Introduces the Wenxin (文心一言) monitoring adapter and registers it in
the runtime controller and adapter index. Adds a new risk_control
failure classification with custom classifiers for Doubao and Wenxin
that recognize rate-limit, 频控 and 访问环境异常 signals, and propagates
this state through account-health, runtime activity alerts, and the
renderer views so users see "触发风控" instead of a generic challenge
message on the Home, Accounts, and AI Platforms screens.
