fix(monitoring): 修復 110 主機 CPU 高負載

CD Pipeline / build-and-deploy (push) Has started running

Details

根因 1: cadvisor 持續掃描 overlay2 磁碟用量 (每次 1-4s × N 容器)
  → 加 --disable_metrics=disk,diskIO,tcp,udp,percpu,sched,process
  → --housekeeping_interval=30s --docker_only=true
  → CPU 從 239% 降到 <1%

根因 2: node_exporter scrape_timeout 預設 10s，高 load 下超時→broken pipe→瘋狂重試
  → 加 scrape_interval: 30s / scrape_timeout: 25s
  → CPU 從 48% 降到 0%

整體 load average: 20 → 9

fix(monitoring): 補齊 blackbox-tcp scrape targets (11→15)

CD Pipeline / build-and-deploy (push) Has been cancelled

Details

SentryDown/HarborDown/SignOzDown 等告警引用的 instance 不在 scrape list
導致 absent metric = 0，告警持續 firing

新增缺少的 targets:
  192.168.0.125:6443/32334/32335 (K3s)
  192.168.0.110:9000/5000/3100 (Sentry/Harbor/Langfuse)
  192.168.0.188:3301/5432/6380/11434/8089 (SignOz/PG/Redis/Ollama/OpenClaw)

已在 110 主機 reload Prometheus，全部 15 targets UP
