后台店铺数据记录页新增 Tab 切换与重复 ASIN 分析；task-169/170 HTTP 客户端配置接入；dedupe/brand 相关改造

- 管理后台：店铺数据记录改为列表分页展示（去任务号/文件列/累计标题，'最新'改'更新时间'），新增'重复 ASIN' Tab 按跨店聚合展示 ASIN/店铺/分组/国家/日期/价格；修复失败/进行中任务被过滤不显示的问题
- task-169: BrandCheckHttpConfigResolver 从 aiimage.http-client.* 读取品牌检查超时/重试（默认同现状、钳制），附 8 条测试
- task-170: surefire 内存调整为 1536m
- dedupe: DedupeRunService 重构（事务边界/进度）、新增 DedupeRunProgressVo、Controller 与结果 VO 调整，PermissionMenuService 相应适配
- brand/dedupe 前端：BrandDedupeTab/BrandPatrolDeleteTab 改造、新增 CountrySelector 组件与 country-options、类型与接口端对齐、测试更新
- 移除无引用文件：backend/static/logo.jpg、prompts/
