refactor: P4c 批次4 服务层改造（role/menu/user_role/role_menu）

- role/menu 走 codemod（get_role_page/get_menu_detail 等 + get_info 委托 Repository）
- menu get_menu_list params 化返回 list；权限函数（get_user_permissions/
  get_user_permission_menus/invalidate_*）保持完整未动
- user_role 已符合新范式（参数化+返回 list）仅验证
- role_menu save_role_menu(data) 改 BizError + router 取参包 R

【验收】flake8 零告警；应用启动；权限函数跨模块运行正常；12 passed
