fix(runtime): onGenerateRoute pathElements 越界 RangeError

- buy-service/renew-minioffice 加长度检查 (pathElements.length >= 4/3)
- 根因: Flutter web 深链接渐进式路径解析, onGenerateRoute 被调用多次,
  pathElements 递增 ([,buy-service] -> [,buy-service,1] -> 完整),
  前几次路径短但 pathElements[1]已匹配 -> int.parse([2])/[3] 越界
- 直接访问/刷新 /buy-service/x/y, /renew-minioffice/x 时崩溃
- 恢复 buy_service 实验代码 (data 校验 + mounted 保留)
