feat: 分销规则完善 + 微信支付修复
1. 分销规则： - 链接带ID绑定推荐关系 - 一级分销 + 30天有效期 - 客户抢夺机制（过期可被抢走） - 90%收益归分发者 2. 新增统计数据： - 绑定用户数 - 链接进入人数 - 带来付款人数 3. 微信支付： - 添加点击反馈 - 优化支付流程日志 - 改善错误提示 4. 分销中心UI优化

* 推荐码绑定API
|
||||
* 用于处理分享带来的推荐关系绑定
|
||||
* 推荐码绑定API - 增强版
|
||||
*
|
||||
* 核心规则：
|
||||
* 1. 链接带ID：谁发的链接，进的人就绑谁
|
||||
* 2. 一级、一月：只有一级分销；绑定有效期一个月
|
||||
* 3. 长期不发：别人发得多，客户会被「抢走」
|
||||
* 4. 每天发：持续发的人绑定一直有效，收益越来越高
|
||||
* 5. 约90%给分发：谁发得多谁拿得多
