Fix Bug #472: 住院医生工作站-手术申请单：勾选手术项目无效，导致无法正常开立医嘱

根因：getSurgeryPage SQL 的 LEFT JOIN 在价格表存在多条记录时产生重复行，
导致 el-transfer 中出现相同 key 的条目，Vue diff 算法无法正确追踪选中状态

修复：
- SQL 添加 DISTINCT ON (t1.ID) 去重（与旧版 getAdviceBaseInfo 一致）
- 前端 applicationList 初始化为空数组 + 过滤空 adviceDefinitionId
- 同步修复 getExaminationPage 的相同问题
