Fix Bug #426: 门诊医生站-检查开立：已选择列表树形展开支持 packageName 解析套餐明细

根因：树形表格懒加载函数 loadPackageDetails 只支持 packageId，但 check_part 表
只有 package_name 字段（无 package_id），导致从左侧分类勾选套餐项目时，
右侧已选择面板能展开（走 loadPackageDetailsForItem），但检查明细树形表格展开为空。

修复：在 loadPackageDetails 中增加 packageName → packageId 解析逻辑，
与 loadPackageDetailsForItem 保持一致。
