fix: PMC 测试清单未完成项 + YYX#row22 未读角标

PMC#16 账户登录地址不正确:
- 写死的 https://airshelf.com/login(不存在的域名)改成 ${location.origin}/login,
  与邀请链接同源,成员拿到的就是当前真实访问地址。

PMC#17/#18 成员三档额度只有月度生效、日/总纯装饰 → 列表显示与配置对不上:
- TeamMember 新增 daily_credit_limit / total_credit_limit(0=不限,迁移 0006);
- reserve_credit 逐档真实管控(每日/每月/累计总额),口径=窗口内 CHARGE 流水 + 在途预留;
- 成员列表"每日额度"由写死"不限"改成真实日额度+今日已用,并新增"总额度"列;
- 创建/编辑弹窗三档额度真入库真生效;补 3 个计费单测(日/总拦截、0=不限)。

PMC#24 同批生成的图片文字/内容雷同:
- 根因=套图/自由创作同批 N 张用同一 prompt 且无变化(只有模特上身图按 index 变);
- 给平台套图/自由参考/纯文生图都加按 index 的版式变体,避开传 seed(防中转站 400)。

PMC#25 重跑应在原任务上重跑而非新开任务:
- 全批"重跑"改为原地复位同一批次卡;"重跑这张/再生成"改为补图进原卡(不覆盖好图、不新开任务)。

YYX#row22 图片生成未读角标(本仓库既有改动一并提交):
- AITask 新增 read_at(迁移 0020 + 索引一致性迁移 0021);导航栏"图片生成"未读胶囊、
  商品预览右下角未读分数;查看某商品即标记其生成任务已读、清零角标。

注:PMC#14/#15/#20/#22/#23 早前提交已修,需部署重测;PMC#13/#21 为 provider 侧
生成失败,代码侧重试/退费/僵尸回收/错误外露已就位,需部署后看真实 error_message 定位;
PMC#19 收件箱标记与设计稿逐字一致,待截图复现。
