v0.1.9

- [ ] 一个渠道，支持配置多个key 这些配置的key，可以增加负载权重，可以点击关闭某个。key 可以点击查看，默认是 ****。之后【使用】这个渠道的时候，这key具备默认负载能力，如果一个挂了，可以请求其他的。
- [ ] 渠道配置，api具备复制能力，复制后方便修改。
- [ ] 【查看日志】，查看的时候，在有调用的时候，主动刷新日志。

The requested behavior covers multiple keys per channel with weighting, disabling, masked-key viewing, and fallback, plus API configuration duplication and automatic log refresh. Done means all three checklist items work together in the desktop UI.
