fix(auto-repair): 中低風險+無kubectl_command → TYPE-1 純資訊，不顯示審核按鈕

問題: HostHighCpuLoad 等主機層告警 affected_services=[] → OpenClaw 生成
kubectl unknown → safety guard 攔截 → 退回 READY + TYPE-3 帶按鈕卡片
用戶一直看到帶按鈕的中/低風險告警，按鈕無法修復任何東西

修復三處:
1. openclaw.py: _call_openclaw_analyze() 回傳 suggested_action 欄位
   + target_resource 預設改為 "" (避免 "unknown" 進入 safety guard)
2. decision_manager.py: classify_notification() 傳入
   suggested_action / risk_level / has_kubectl_command
3. telegram_gateway.py: classify_notification() 新規則 —
   無 kubectl_command + risk=low/medium + action=investigate/no_action
   → TYPE-1 (純資訊，無按鈕)

搭配 clawbot-v5 f4b84d7 (OpenClaw prompt CRITICAL RULES) 一起生效
