cleanup: 删除Step5未使用的templateName/materialCount/duration props传递链 (#1396)

- Step5GeneratePreview: 移除接口声明+解构中未使用的3个字段
- GenerateStepContent: 移除previewTemplateName/previewMaterialCount接口+解构+传递
- GeneratePage: 移除传递给GenerateStepContent的2个prop
- 保留useStep5Preview hook计算逻辑(useStep7Generate SummaryCard仍在使用)
