refactor: 移除资源用量的可选 Prometheus 接入与平台监控页

- 资源用量弹窗:删除 applyPrometheus/promQueryValue 与峰值/限流字段
  (LOKI_USAGE_PROMETHEUS_URL 从未内置,代码恒走降级),统一提示
  「未接入 Prometheus:暂无峰值/限流数据」;扩容建议改基于 metrics-server 实时值
- 移除「平台监控」菜单页与 /api/v1/system/metrics-summary;
  原始指标保留在标准 /api/v1/metrics(Prometheus 文本格式)可自行抓取
- 手册/落地页/CHANGELOG 同步(去除备份恢复与监控页宣传,指标端点表述中性化)

CHANGELOG.md

@@ -7,11 +7,12 @@
 
 ### 移除
 - 备份恢复功能(含 API / CLI / 手册):日志数据本体的保留与安全由对象存储与 Loki retention 承担,平台侧备份价值有限
+- 平台监控页与 `/api/v1/system/metrics-summary`:原始指标仍经标准 `/api/v1/metrics`(Prometheus 文本格式)暴露,可自行抓取
+- 资源用量弹窗的可选 Prometheus 接入(峰值/限流查询):统一以「未接入 Prometheus:暂无峰值/限流数据」提示,扩容建议基于 metrics-server 实时值
 
 ### 新增
 - 落地页(homepage/,`/homepage` 访问):产品介绍、特性、快速开始
 - 用户手册文档站(docsify,`/docs` 访问):安装、部署向导、采集、查询、分析、告警、授权、备份、FAQ 十篇
-- 平台自监控(`/monitor`,管理员):请求量/5xx/DB 大小/Goroutines 统计卡,Top 路由、状态码、告警评估、Loki 查询与落盘明细(后端 `/api/v1/system/metrics-summary` 快照端点)
