feat: 接入 USDT-M 合约数据 — type 字段方案
- PairType 定义移至 types/kline.ts (spot/um/cm) - Kline 接口新增 type 字段,全链路透传 - klines 5列复合主键 (exchange, symbol, type, interval, time) - 拆出 BinanceFuturesRestClient (USDMClient) - exchanges/index.ts 注册 binance_futures - trading_pairs 唯一约束加 type,种子数据加合约对 - 12个连续聚合视图 SELECT/GROUP BY/INDEX 加 type - 清理 bnkline.ts 废弃代码和 pair.ts 空函数
