Fix Bug #476: 住院医生工作-检查申请单界面缺失核心临床字段（紧急程度、过敏史、检查目的等）

在检查申请单开立界面新增5个核心临床字段（依次放在发往科室之后）：
1. 紧急程度：el-select下拉选择（普通/急诊），区分急诊和普通检查
2. 过敏史：textarea输入，提示造影剂过敏风险
3. 检查目的：textarea输入，让执行科室医生了解临床背景
4. 病史摘要：textarea输入，补充患者病史信息
5. 期望检查时间：datetime选择器，实现精准调度

同步更新：
- medicalExaminations.vue: 表单模板 + form reactive对象新增字段
- examineApplication.vue: labelMap映射 + 详情弹窗紧急程度转换 + 修改弹窗新增字段 + 编辑/保存逻辑覆盖新字段
