feat(analytics): 数据分析页增加访问与受控设备的国家维度分布
参考受控版本分布的饼图实现,新增国家维度分布: - AnalyticsDailyDim 增加 KIND_VISIT_COUNTRY / KIND_DEVICE_COUNTRY 常量 - AnalyticsReportService::aggregateDay() 按 country 聚合访问 UV 与受控设备数 - present() 汇总并返回 by_visit_country / by_device_country(ISO 代码转中文名展示) - 视图新增两个国家饼图卡片与两个国家明细标签区 性能与正确性修复: - ensureCached() 改为一次查询校验所有按日聚合 kind 的缓存完整性, 避免旧缓存完整时新维度不被聚合的问题 - 新增迁移为 page_visits / devices 建立 (created_at, country) 复合索引, 对齐 os_version 维度的索引做法,加速按日期范围 + GROUP BY country 的聚合
