[BUG] <title>对K8S的nodes、namespaces、pods、services告警产生的BUG

### Is there an existing issue for this?

- [ ] I have searched the existing issues

### Current Behavior

新增实时阈值规则

1、指标类型选择 Kubernetes/Pod

2、最终总表达式：
equals(__app__,"kubernetes") && equals(__metrics__,"pods") && equals(__instance__, "554840282830848") && equals(status, "Failed")

3、数据60s采集一次，5分钟后没有产生告警

### Expected Behavior

对上述的阈值配置产生对应的告警内容，每个符合条件的nodes、namespaces、pods、services应该都产生告警内容

### Steps To Reproduce

_No response_

### Environment

```markdown
HertzBeat version(s):
```

### Debug logs

_No response_

### Anything else?

_No response_

Start by reproducing the reported Kubernetes/Pod real-time threshold rule using the expression and 60-second collection interval described in the issue. Check how matching nodes, namespaces, pods, and services are evaluated for alert generation. Done means each matching resource produces the expected alert; the issue provides no files or tests to guide the investigation.
