卡若 991e17698c feat: 内容管理第5批优化 - Bug修复 + 分享功能 + 代付功能
1. Bug修复:
   - 修复Markdown星号/下划线在小程序端原样显示问题(markdownToHtml增加__和_支持,contentParser增加Markdown格式剥离)
   - 修复@提及无反应(MentionSuggestion使用ref保持persons最新值,解决闭包捕获空数组问题)
   - 修复#链接标签点击"未找到小程序配置"(增加appId直接跳转降级路径)

2. 分享功能优化:
   - "分享到朋友圈"改为"分享给好友"(open-type从shareTimeline改为share)
   - 90%收益提示移到分享按钮下方
   - 阅读20%后向上滑动弹出分享浮层提示(4秒自动消失)

3. 代付功能:
   - 后端:新增UserBalance/BalanceTransaction/GiftUnlock三个模型
   - 后端:新增8个余额相关API(查询/充值/充值确认/代付/领取/退款/交易记录/礼物信息)
   - 小程序:阅读页新增"代付分享"按钮,支持用余额为好友解锁章节
   - 分享链接携带gift参数,好友打开自动领取解锁
