docs(backup): 備份審計完整盤點 + 新增 AWOOOI DB 與 Gitea DB 備份腳本

首席架構師備份審計結論：
- awoooi_prod PostgreSQL：❌ 無備份 (P0 缺口)
- Gitea SQLite DB：❌ 無備份 (今日已損壞，人工修復耗時 2h+)

新增:
- scripts/backup/backup-awoooi-db.sh (188 部署，02:00 daily)
- scripts/backup/backup-gitea-db.sh (110 部署，01:00 daily)
- docs/runbooks/BACKUP-STATUS.md (全景表 + 部署步驟 + SOP)
- LOGBOOK.md 備份審計段落

待手動部署：統帥需 scp 腳本至 188/110 並設定 crontab
