feat(后台管理): 实体管理列表统一展示创建时间/更新时间

用户管理、菜单管理、不符合ASIN、数据去重总数据、查询ASIN、最低价ASIN、
商品类目、密钥管理共 8 个实体管理列表补齐两列。分组管理/店铺密钥/店铺管理
此前已带创建+修改时间，任务列表与统计报表（撞款监控、密钥用量、日志、
记录与版本）不含实体更新语义，均未改动。

关键点——时间列必须由数据库维护，否则新列是假的：
这些表的更新走 selectById → 改字段 → updateById，实体带着读出的旧
updated_at 一起写回。MySQL 规则是「UPDATE 显式给某列赋值时不触发该列的
ON UPDATE 自动更新」，不禁写就会把旧值写回去，更新时间永远冻结在首次写入
时刻。按 V125（biz_file_result）既有样板，给 7 个实体标注
@TableField(insertStrategy=NEVER, updateStrategy=NEVER)。

- V131：users / columns 补 updated_at（幂等 ADD COLUMN，仿 V125 写法）。
  存量行被回填为迁移执行时刻，非真实历史变更时间（历史上无记录，无法还原）
- 实体/VO：AdminUserEntity、PermissionMenuEntity、InvalidAsinDataEntity、
  DedupeTotalDataEntity、ProductCategoryEntity、QueryAsinEntity、
  SkipPriceAsinEntity 加/改写 updatedAt；AdminUserItemVo、PermissionMenuItemVo、
  InvalidAsinDataItemVo、DedupeTotalDataItemVo 补 updatedAt；
  AdminUserSecretRowVo 补 createdAt（行级首次配置时间 = 三模块最早）
- 查询ASIN/最低价ASIN 后端 VO 与前端 model 本就有两字段，仅补渲染
- 前端 8 页表格加列，同步修正空态/加载行的 colspan（手写表格，不同步会错位）
- 测试：align-query-asin / align-skip-price 原断言「不允许有更新时间列」
  （像素复刻旧版），按新需求改为断言两列存在；新增 e2e list-time-columns
  覆盖 8 页表头与真实时间值渲染
