feat(infra): 切換 Ollama 到 M1 Pro 192.168.0.111 + NetworkPolicy 更新

- OLLAMA_URL: 188 → 111 (M1 Pro, 40+ tok/s vs 0.45 tok/s)
- OPENCLAW_DEFAULT_MODEL: qwen2.5:7b-instruct → deepseek-r1:14b (SRE最強推理)
- OPENCLAW_TIMEOUT: 90s → 120s (deepseek-r1:14b 實測最慢 54s)
- NetworkPolicy v1.3: 新增 192.168.0.111:11434 egress，移除 188 的 Ollama port
