Fix Bug #507: [住院护士站-住院记账-补费] 项目单位未获取、执行科室显示内码且缺乏默认/模糊搜索逻辑

根因分析：
1. 执行科室显示内码：loadDepartmentOptions 只读取树形结构的第一层（records[0].children），
   但后端返回的是多层嵌套的树形数据。修复为递归扁平化 flattenTree() 提取所有科室节点。
2. 单位字段为空：getUnitCodeOptions 中 unitCode_dictText/minUnitCode_dictText 为 null 时，
   option 的 codeText 为 null 导致 el-select 无法显示。修复为 fallback 到 code 值本身。
