fix(viral-video): 分析/生成期间不再锁定页面其他控件（P0）

- 移除 canEditAssets 限制，STEP1 上传/音色/参考视频/参考音频等控件在分析图片期间全程可操作
- 移除 canEditStep2 限制，STEP2 融合方式/输入框/参数 Select 在生成文案期间全程可操作
- STEP3 4个参数 Select（视频比例/模型/清晰度/超分）生成视频前后均可改
- 分镜脚本 storyboard inline 编辑在生成视频前后均可改（locked=false）
- 只保留三个主按钮自身的 loading + disabled 防重复提交：
  - 分析图片按钮：step1_analyzing 时 disabled+spinner
  - 生成文案按钮：step2_generating 时 disabled+spinner
  - 生成视频按钮：step3_generating 时 disabled+spinner
- 图片列表项保留单图上传中的 uploading 锁（防止正在上传的图被删/移动）
- 无 pointer-events:none、无容器 disabled、无全屏遮罩
