[susu] 创建按钮详情请求失败

Error message

[susu] 创建按钮详情请求失败: %w

What it means

http.NewRequestWithContext rejected the susu button-detail POST target (ButtonDetailURL) or its body. Fires only on a malformed URL or unreadable reader — the site has not been contacted yet. Input at fault: the configured ButtonDetailURL constant.

Solutions

1. Validate ButtonDetailURL at init
2. This is a programming/config bug, not a runtime condition: fix the constant
