实现先进行风险阈值过滤，再按最坏效用、期望效用和名称进行确定性选择。

仅在 ruin_risk<=0.20 的可行集中按 (-worst_case_utility, -expected_utility, name) 排序并返回首项。

若输入结构无效、数值不可解析或所有候选超出风险阈值，函数将返回 None。

该实现先做风险约束过滤，再按稳健优先级进行确定性排序选择。

仅保留 ruin_risk<=0.20 的候选，并以 (-worst_case_utility, -expected_utility, name) 作为排序键返回首项。

若输入不是列表、字段缺失或数值不可解析，相关候选会被跳过，可能返回 None。
