feat(ollama): ADR-110 GCP 三層容災架構（GCP-A → GCP-B → Local → Gemini）

## 變更摘要
- Primary: http://34.143.170.20:11434 (GCP-A SSD, 9x 載速 + 2x 推理)
- Secondary: http://34.21.145.224:11434 (GCP-B SSD)
- Fallback: http://192.168.0.111:11434 (M1 Pro Local HDD，最後防線)
- 廢止 ADR-105「111 唯一鐵律」，新建 ADR-110

## 核心改動
- config.py: 新增 OLLAMA_SECONDARY_URL；validator 加 GCP IP 白名單（34.143.170.20, 34.21.145.224）
- ollama_failover_manager.py: 三層 Ollama 決策矩陣；並行健康檢查三台；health_111 → health_gcp_a
- ollama_health_monitor.py: host label 萃取改為通用版（支援 GCP 公網 IP）
- failover_alerter.py: 故障/恢復主機動態顯示，不再硬編碼「Ollama 111 (GPU)」
- ollama_auto_recovery.py: notify_recovery 改為 ollama_gcp_a；recovered_host 動態
- k8s/awoooi-prod: configmap + deployment + network-policy 同步更新（egress 加 GCP /32）
- 服務層: 10 個服務檔案硬編碼 192.168.0.111 改為讀 settings.OLLAMA_URL
- 測試: URL 常數更新，新增三層容災場景，GCP IP 白名單驗證測試
