fix(prometheus_url): drift 殘存追修 — kured 守門員 + monitoring API

debugger 全 codebase 追根溯源後揪出 5 處 PROMETHEUS_URL drift 殘存
(根因:docs/reference/SERVICE-ENDPOINTS.md 早期把 Prometheus 標在 188
是整個 codebase drift 的源頭)。

本次修最急的 2 處:

## 🔴🔴 kured.yaml:132(守門員失效風險)
- 188 → 110
- kured 跑 reboot 前會查 Prometheus alerts,連錯主機 = 跳過保護直接 reboot 主機
- 對齊 ConfigMap + config.py PROMETHEUS_URL

## 🟡 monitoring.py:67(單一事實源)
- 寫死 110:9090 改用 settings.PROMETHEUS_URL
- 主機巧合正確但繞過 ConfigMap 注入機制
- 未來 Prometheus 再遷移避免再次 drift

## 暫不修
- k3s_monitor_service.py:38 用 121:30090 是 K3s NodePort 內網端點
  與外部 PROMETHEUS_URL 概念不同,需新增 PROMETHEUS_INTERNAL_URL setting
- 其他 docstring + 文件 drift(SERVICE-ENDPOINTS.md 等)留待後續

## 驗證
1552 unit tests 全綠(無回歸)
