Fix Bug #489: 【医嘱闭环】医生站签发单条长期药品医嘱，护士校对界面生成重复（两条）待校对记录

根因分析：
1. SQL查询JOIN倍增：selectInpatientAdvicePage 中多个LEFT JOIN（如adm_encounter_location、
   adm_encounter_participant、med_medication）可能产生重复行，外层查询无DISTINCT去重
2. 防重复逻辑缺陷：handMedication() 中仅对 DbOpType.INSERT 进行去重，若同一请求中包含
   INSERT 和 UPDATE（编辑后签发的医嘱），两者uniqueKey相同但UPDATE不受去重限制，
   导致 UPDATE 修改旧记录 + INSERT 创建新记录 = 两条数据

修复方案：
1. 在AdviceProcessAppMapper.xml的UNION两侧子查询中添加SELECT DISTINCT，防止JOIN倍增
2. 在AdviceManageAppServiceImpl.java中移除dbOpType限制，对所有医嘱（INSERT+UPDATE）
   统一按uniqueKey去重，确保同一业务医嘱只处理一次
