Description

断路器触发时，能否提供一个指示器？显示哪个API的断路器状态是打开的或者关闭的。最好直接显示在控制台上。xxx Open xxx Closed 这样使用体验会好很多。 而且有状态之后可以做很多事情，比如一旦打开，就推送告警之类的。

同理，还有限流、系统负载过高等等都可以提供一下状态显示。。。比如限流中、负载高等等。目前控制台感觉显示不够直观。 作为开发，可能并不是特别关注QPS，我更加关注的是现在API是不是处于正常的状态。如果不在正常状态，就去介入。

Research direction
Check the Sentinel console code in the sentinel dashboard module, particularly the circuit breaker dashboard (e.g., SentinelDashboardController). The issue requests a status indicator for each API's circuit breaker open/closed state. Review the existing metrics display and consider adding a new panel. There is an assignee, but no linked PR, so scope is unclear. Look for any design discussions in comments.
