fix(video): 视频片段数对齐采用版分镜数,修「删分镜后视频步骤仍显示旧数量」

项目创建固定铺 4 段视频片段,而 _sync_video_segments_to_script 仅在增删分镜且该脚本 is_adopted 时才收口。用户通常「采用前」就增删分镜, 那些编辑被 is_adopted 闸跳过;adopt_script 自身又不收口 → 视频步骤一直停在 4 段,与故事板/采用版分镜对不上。 - adopt_script:采用时按这版分镜数收口视频片段 - poll/skip-storyboard:进入视频阶段前再收口一次(安全网) - retrieve:视频阶段详情加载时自愈历史脏项目(只裁从未生成过的尾段) - 已生成/生成中的段绝不动;新增 3 个回归测试 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
