fix(#630): 修复 getOne() 多条记录异常 — 仅修改查询条件，不改方法签名

根因：4处 emrService.getOne() / docRecordService.getOne() 调用
缺少 orderByDesc + LIMIT 1 和第二参数 false，当同一 encounterId
对应多条病历记录时抛出 IncorrectResultSizeDataAccessException。

修复（仅查询条件，不改接口签名）：
- Line 78: addPatientEmr 添加 orderByDesc + LIMIT 1 + false
- Line 148: getEmrDetail(Emr) 添加 orderByDesc + LIMIT 1
- Line 154: getEmrDetail(DocRecord) 已有 false 参数
- Line 277: checkNeedWriteEmr 添加 orderByDesc + LIMIT 1 + false

编译验证：mvn compile BUILD SUCCESS ✅
