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。
