test: 所有测试适配 PathEntry[] 类型，新增 TOGGLE undo/redo 测试

- undo-redo.test.ts: 所有 11 项测试通过（含新增 TOGGLE 撤销/重做）
- app-store.test.ts: 断言改用 .map(e => e.path)，待 Task 5 修复
- import-export.test.ts: sampleData 改用 pe()，导出断言适配
- path-manager.test.ts: 测试数据用 pe() 包裹，待 Task 3 修复
- validation.test.ts: 无需变更（纯 string 接口）
