fix(viral-video) P0: 修复GET /models响应包装导致页面白屏，数组操作加防御

根因：后端 GET /api/v1/viral-video/models 返回 {"models": [...]} 包装对象，前端 getViralVideoModels() 声明返回 ViralVideoModel[] 并在 .then 直接对 r.data 调 .some()，实际 r.data 是对象而非数组，导致 TypeError: s.some is not a function 白屏。修复： - 新增 ViralVideoModelsResponse 类型 - getViralVideoModels() 改为泛型 ViralVideoModelsResponse，解析时兼容数组/包装两种返回 - 模型加载 useEffect：list/supported_resolutions 加 Array.isArray 防御 - 模型切换 onChange：m.supported_resolutions 加防御兜底 [480p,720p,1080p] - 清晰度 Select 过滤池：curM?.supported_resolutions 加 Array.isArray 守卫 - options 渲染：filter 掉非对象空项，label fallback 到 key - max_duration 加 typeof === 'number' 防御
