fix: 修复账号批量操作快捷多选不生效和今日 Token 不准确 (#328)

* fix(pool): 修复账号批量操作快捷多选不生效

- 解析号池账号列表接口的 quick_selectors 查询参数
- 列表查询复用现有快捷筛选匹配逻辑
- 支持冷却列表与普通列表的快捷筛选后分页
- 更新架构测试中的 pool admin helper 边界断言

* fix(dashboard): 今日 Token 改为按分项汇总口径展示

- /api/dashboard/stats 的 today.tokens 改为 输入+输出+写缓存+读缓存
- “今日 Token”卡片 value 与 subValue 口径保持一致
- 同步更新 dashboard 相关测试断言
