fix(frontend): 统一计数缩写口径并将流水号改为订单号

前台各处评论、浏览、点赞、收藏、已售数量统一走
aksrt_format_number() 缩写（≥10000 → 1.2W+，≥1000 → 1.5K），
缩写后缀统一为大写 K，与既有 W+ 保持一致。PHP 渲染缩写文本的
同时保留 data-base-count 原始整数，JS 增量计算不受影响；
article.js / comment-ajax.js 内的 formatStatCount / formatCount
与 PHP 规则保持同一套，避免点赞收藏后文本回跳成全量数字。

文章详情页购买信息卡、用户中心创作者收益明细、后台分成与提现
管理页、支付设置页以及四封订单/提现邮件模板中，面向用户展示的
「流水号」字样统一改为「订单号」；代码注释、内部错误码与
WP_Error 文案保留原表述。

验证：node --test "tests/*/*.test.cjs" 508 项全部通过；
php -l 检查全部改动文件无语法错误；重新构建 admin SPA 与
前台 runtime bundle。
