feat: 风险页新增数值修改、一键跑图与万花筒专区

- 修改总 Rating：只写 playerRating 与 userRating.rating，钳 0~99999，
  每首歌各自的 ratingList 原样带回
- 添加舞里程（UserDetail.point）：完整 int32 区间，支持累加与直接设定，
  允许负值即扣减
- 一键跑图：isClear/isComplete 在客户端是从 distance 派生的，单发 flag 会被
  冲掉，故把 distance 推过 End 里程针；unlockFlag 语义是反的
- 万花筒专区：发现门与获取钥匙落在 userKaleidxScopeList 同一行的两个布尔位，
  钥匙不走 userItemList；上行是整行替换，所以先读回原行再叠加
- 旅行伙伴：修正误导性的示例 ID 1001（合法是三位数，表里没有的 ID 服务器照收
  但客户端静默跳过），编组槽位可设定等级，上传后回读复查以区分失败原因
- 补 MIT 许可证
