Fix Bug #465: [住院医生工作站-检验申请] 检验项目选择列表被限制为500项，导致医生无法检索并开立其余800多项

问题根因:
- 前端使用 pageSize=500 分页拉取数据，el-transfer 组件客户端过滤在 1400+ 条数据下存在渲染和搜索性能问题
- 数据库实际有 1400 项已启用的检验类诊疗项目，但仅加载了 500 项

修复方案:
1. 改用 pageSize=9999 一次性拉取全部数据，消除分页导致的 500 项截断
2. 新增顶部搜索框，支持按项目名称/拼音首拼/业务编号实时过滤
3. 使用 computed 属性动态生成 transfer 组件数据，搜索时自动过滤
4. 显示总数统计（未搜索时显示总数，搜索时显示匹配数/总数）
5. 移除不再需要的 applicationList 变量引用和 onBeforeMount 空调用
