liuwenxinandClaude Code 5ece9f6dab refactor(backend): 仓储层散参数收敛为查询 DTO
仓储层的 list_*/count_* 此前以 keyword/status/offset/limit 四五个散参数
传参,调用点重复铺开、易漏传且不可扩展;按项目「参数 >4 封装 DTO」的
约定统一收敛为各模块的 Query 对象(如 RoleQuery、BusinessQuery),
服务层与测试调用同步调整,行为不变。

- repositories 层查询方法签名改为 (session, query),分页与筛选条件
  由 Query 承载,_apply_filters 同步收口
- schemas 层补齐各模块 Query 模型(approval/business_role/report 等)
- services 层调用点同步改为传 Query
- tests 随之调整;新增用例:待办角色流转(财务通过后领导出现待办)、
  参数预览顺序稳定

验证:全量 pytest 900 passed(11:08);单元 526 passed;ruff check 绿。
