refactor(video): 重构视频配置参数标准化逻辑

- 将视频配置参数标准化逻辑提取为独立的 buildVideoConfig 函数
- 添加视频秒数、尺寸、清晰度的标准化验证函数
- 限制视频秒数只允许 6/10/12/16/20 秒的预设值
- 验证视频尺寸格式是否为标准的宽高比格式
- 优化视频生成 API 调用的错误处理机制
- 统一错误消息显示，修复页面残留生图参数影响视频请求的问题

 - 视频清晰度输入框改为只输入数字，提交请求时再拼接 `p` 单位。
 - 视频生成前端会识别后端 `{ code, msg }` 错误响应，创建失败不再继续轮询 `undefined`。
 - 新增 `/video` 视频创作台页面，参考生图工作台布局，支持提示词、参考图、视频参数、生成结果、保存素材、下载和本地生成记录；清晰度和秒数均支持常用值选择与手动输入。
+- 视频创作台生成前会把模型、尺寸、秒数、清晰度归一化为视频接口支持的参数，并展示后端返回的错误信息，避免页面侧残留的生图参数影响视频请求。
