fix(backup): HostBackupFailed P1 根治 — Prometheus textfile 指標 + docker socket 讀取
問題一：backup_110_last_success_timestamp 指標從未存在
根因：腳本只寫純文字 last_success 檔，從未輸出 .prom 格式
修復：成功時寫入 /home/ollama/node_exporter_textfiles/backup.prom
node_exporter 新增 --collector.textfile.directory=/textfile_collector
volume: /home/ollama/node_exporter_textfiles:/textfile_collector
問題二：Harbor/Gitea rsync 權限拒絕
根因：/var/lib/docker/volumes/ 是 710 root:root，docker group 無法直接存取 FS 路徑
修復：改用 docker run --rm -v <volume>:/source alpine tar czf -
透過 docker socket（wooo 已在 docker group）讀取 volume 內容再解壓
驗證：備份腳本三項全 OK，node_exporter 9100/metrics 正確輸出指標
Prometheus absent(backup_110_last_success_timestamp) 應在下次 scrape 後清除
