feat(core): 脚本 agent 真流式思考动画 + 场景图16:9 + 资产卡/审核标修复 + 模型收敛

- 进度区改竖线时间轴:推理模型 reasoning_content 逐字转发(volcano),状态字=模型实时最新一句+秒数+折叠展开思考全文(替代旧 ProgressStream/ThinkingStream)
- 场景基础资产出图改 16:9(run_base_asset_task size + 提取提示词横屏)
- 已出图立绘主卡不再被在途轮询任务误盖转圈
- 审核态随项目详情持久下发(BaseAssetGroup.adopted_asset_review),刷新不丢徽章
- 设定卡加「← 返回」回三选项;模型选择器固定按 created_at 排序(默认豆包2.0Pro)
- 新增 reasoning 转发回归测试
