fix: keep Chinese downloads on OSS loading state

The Chinese download cards briefly exposed the GitHub fallback before OSS index validation completed. They now stay disabled while loading and only show GitHub if the OSS request or validation fails; English downloads remain unchanged.

Release note: 中文官网下载入口加载 OSS 索引期间不再短暂跳转 GitHub，仅在索引失败时回退。
