fix: Bug #609 - 出院申请 Index:0 IndexOutOfBoundsException

Root Cause: SpecialAdviceAppServiceImpl.saveLeaveHospitalOrders()
在第 436 行调用 .getRecords().get(0) 时，如果 getAdviceBaseInfo
返回空列表，会抛出 IndexOutOfBoundsException。

Fix:
1. 用 CollectionUtils.isEmpty() 判空，空时返回友好错误提示
2. 修复 endTime = endTime 的无操作逻辑，改为默认当前时间
