refactor(exchanges): fetchKlines 改为 params 对象签名，新增 type/exchange 参数

- 新增 FetchKlinesParams 接口统一 fetchKlines 参数（exchange/type/symbol/startTime/limit/endTime）
- BaseRestClient 抽象方法 + MarketDataFeed 接口改为 params 对象签名
- BinanceRestClient / BinanceFuturesRestClient 由调用方传入 type，不再硬编码 spot/um
- index.ts 新增静态 fetchKlines(params) 便捷函数，按 exchange+type 自动路由
- exchange.ts / bnkline.ts 调用方适配新签名
- 初始化 SQL 补充 BNBUSDT/SOLUSDT 合约交易对
