feat(业务用户组): AUG26-003 业务用户组与店铺负责人分组导入

- 迁移 000221：新增 tb_business_user_group、tb_business_user_group_member、tb_shop_business_owner_import_task，成员一账号一行由部分唯一索引保证，店铺所属组按当前负责人实时推导，不回填历史分组。
- 用户组 CRUD、成员改组/清空归属、店铺批量交接（原子失败不部分写入）。
- 店铺负责人 CSV 导入任务：逐行独立事务、逐行明细、任务级与行级失败分离。
- 读侧推导与筛选：未分组、业务线、停用组可筛出并带停用标记。
- 补齐操作审计动作与资源、openapi 清单、发布门禁巡检表清单。
- 归档 add-shop-salesperson-groups 变更并同步 openspec/specs/business-user-group，补齐 AUG26-003 验证证据链。
