fix(P0-02): 积分榜改为追加快照(append-only) + available_at cutoff

去掉 uq_standings_league_season_team,改为 (league, season, team, available_at) 唯一;
每次采集 INSERT 新行(available_at=now),ON CONFLICT DO NOTHING,不覆盖旧行。

standings_slice(before):DISTINCT ON (team_id) WHERE available_at<=cutoff
ORDER available_at DESC;before=None → cutoff=now()。
公开 list_standings 取每队最新可用快照(子查询 max available_at)。

迁移 0023 + 切片/路由/docs 同步;测试 test_p0_standings_cutoff(5/5)。
284 测试全绿。

+## 同站部署 vs 跨站 CSRF
+
+ Profeto 管理鉴权使用 **HttpOnly Cookie 会话**(登录后服务端写入),`allow_credentials=True` 的 CORS 配置允许浏览器跨域携带 Cookie——这也引入了 CSRF 面。部署拓扑决定风险等级:
+
+**同站部署(推荐)**: 前端与 API 同域(反代把 `/` 与 `/api` 都转发到同一后端,或同源端口)。
+  - 浏览器视为 **same-origin**,CORS 不触发;`SameSite=Lax` 会话 Cookie 天然阻断跨站请求携带。
+  - 风险最低。`CORS_ORIGINS` 可设为空或同域来源,仅作兜底。
+
+**跨站部署**: 前端与 API 不同域(如前端 `app.example.com`、API `api.example.com`,或开发时 `localhost:3000` → `localhost:8000`)。
+  - 必须把 API 域名列入 `CORS_ORIGINS`,且 `allow_credentials=True` 才能携带 Cookie。
+  - 此时任何被允许域下的页面都能构造带 Cookie 的请求 → **CSRF 面**:
+    - 状态变更接口(采集/回测/改密等写操作)要求**管理员 Cookie + 同域**,攻击者无法从第三方站点读取 Cookie,但可构造跨域表单/请求——`SameSite=Lax` 会阻断跨站 POST 表单提交(顶级导航 GET 仍放行),这是当前主要防线。
+    - `GET /api/v1/admin/*` 只读接口受 `SameSite=Lax` 下顶级导航可能被利用,但攻击者无法读取响应(CORS 不匹配时浏览器拦截)。
+  - **加固建议**:
+    1. 反代层加 `Origin`/`Referer` 校验,仅放行 `CORS_ORIGINS` 列表中的来源(即便 FastAPI CORS 已通过,反代校验是多一层纵深)。
+    2. 写操作要求自定义请求头(如 `X-Requested-With: XMLHttpRequest`),第三方站点无法在无预检下添加自定义头,天然阻断简单跨站 POST。
+    3. 生产强制 HTTPS(`APP_ENV=production` 下 Cookie 自动 `Secure`),防中间人窃 Cookie。
