chore: retrigger CI - final attempt

- Step5GeneratePreview: 移除接口声明 templateName/materialCount/duration + 解构 _templateName/_materialCount
- GenerateStepContent: 移除接口声明 previewTemplateName/previewMaterialCount + 解构 + 传递给Step5的3个prop
- GeneratePage: 移除传递给GenerateStepContent的previewTemplateName/previewMaterialCount
- 保留 useStep5Preview hook 中的计算逻辑（useStep7Generate SummaryCard 仍在使用）
