Replay the project preview aggregation changes on the latest main and retain the card-thumbnail fallback test.
Resolve the project page test conflict by preserving the single-request preview flow and the card-thumbnail fallback coverage.

检查了项目预览的后端聚合契约、前端消费路径,以及该替代提交与当前 main 的实际三方合并结果。批量接口消除了请求瀑布,但当前分支仍无法合并,并且预览搜索范围比原实现缩窄,会把仍有可用素材的项目显示为空。
验证:GitHub 返回 mergeable=false / mergeable_state=dirty,本地固定 SHA 三方合并复现了冲突;原前端实现与新 SQL 排名条件的调用链已逐项比对。测试未能在此运行环境启动:后端缺少 uv/pytest,前端未安装 node_modules。

[P1] 将替代提交真正建立在当前 main 上
此 PR 的说明称提交已直接重建在当前 main,但 13ca792 的父提交仍是 57aca58,而不是本次基线 5ebe10a。GitHub 当前也返回 mergeable=false / dirty;按这两个固定 SHA 做三方合并时,frontend/src/pages/projects/index.tsx、对应测试和 openapi.json 都产生冲突。因此这个用于解决冲突的替代 PR 仍然无法合并;请从 5ebe10a 重新创建/拣选该提交并解决这些重叠改动。

[P1] 不要只检查最近六个角色的预览
原来的前端逻辑以每页 6 个角色持续翻页,直到找到预览或遍历完整个项目;这里却在 SQL 层永久丢弃 project_rank > 6 的角色。只要最新六个角色都没有图片、较早角色仍有造型/参考图/帧,列表就会返回 preview_url: null 并错误显示“等待第一份角色资产”。请在单次批量查询中搜索全部角色(例如直接选出每项目首个非空预览),而不是用固定数量截断语义。

Why
项目列表直接交付每个项目的可用资产预览,并移除项目中心逐项目读取 Character 的请求队列,使一页项目只需一次业务 API 请求。
Conflict resolution
This replacement preserves the exact resolved source tree from #431, but rebuilds it as a single commit directly on current
mainto avoid GitHub's persistent falsedirtymergeability state.Supersedes #431 for merging purposes.
