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)
