/**
 * OKX 网格交易模块全局配置，策略的唯一参数入口。
 *
 * <h3>定位</h3>
 * 通过 Builder 模式将所有运行参数集中管理，避免策略参数散落在多个类中。
 * 运行时动态参数（step、gridElements、baseLongTraderParam、baseShortTraderParam）
 * 由 {@link OkxGridTradeService} 在策略执行过程中写入。
 *
 * <h3>参数分类</h3>
 * <table>
 *   <tr><th>类别</th><th>参数</th><th>用途</th></tr>
 *   <tr><td>认证</td><td>apiKey, secretKey, passphrase</td><td>REST/WS 签名认证</td></tr>
 *   <tr><td>交易标的</td><td>instId, leverage, quantity, ctVal</td><td>合约、杠杆、张数、面值</td></tr>
 *   <tr><td>持仓</td><td>tdMode, posSide</td><td>全仓/逐仓、多/空</td></tr>
 *   <tr><td>网格策略</td><td>gridRate, gridQueueSize, priceScale</td><td>间距比例、队列容量、价格精度</td></tr>
 *   <tr><td>止盈止损</td><td>expectedProfit, maxLoss</td><td>整体止盈/亏损阈值（USDT），触发后策略重置</td></tr>
