fix(core): 删脚本分镜联动删故事板帧 + 演员库自取 person + 分镜编辑行抽组件

- views.py: delete-script-segment 同步删对应 StoryboardFrame(原 SET_NULL 留孤儿帧致故事板仍显示已删的场),并重排剩余帧 sort_order
- actor-library.tsx: 演员库改自取 person 资产(全局 assets 已懒加载不再全量预载,否则演员库全空),保存后 reload 即时入列
- pipeline.tsx: 抽出 EditableShotField 组件、PromptBox 参数化
- 附 perf-report 产物
