- 放宽_finalize_render_success写表条件：只要有generation_task_id就写，不依赖project_id
- 新增历史数据补写脚本scripts/backfill_generated_videos.py
- 新增5个单元测试验证逻辑
- 一键生成场景(project_id为空)的视频渲染成功后会正确写入generated_videos表

+"""补写 generated_videos 记录 — 修复一键生成场景下 project_id 为空导致未写表的问题.
+
+背景：#535 之前的一键生成场景，由于 edit_plan.project_id 为空，
+_finalize_render_success 中 `if generation_task_id and project_id:` 判断不通过，
+导致渲染成功的视频没有写入 generated_videos 表，成片库看不到。
+
+本脚本扫描所有 status=completed 的 generation_task，
+如果没有对应的 generated_videos 记录，则从 plan.config.rendered_url 补写。
+
+用法：
+    PYTHONPATH="apps/worker:apps/api:packages" python scripts/backfill_generated_videos.py
+
+安全说明：
+- 只读事务扫描，补写前检查是否已存在，不会重复写入
+- 失败不中断，继续处理下一个
