feat(order): show estimated RR before open across four exchanges

Add shared manual_order_rr_preview.js to fetch order_defaults after symbol and TP/SL inputs complete, display estimated profit-loss ratio before submit in price and percentage modes (and fixed RR), unified for risk and full-margin sizing.

+# 实盘下单 · 预估盈亏比
+
+## 功能
+
+四所（Binance / OKX / Gate / Gate趋势）**实盘下单监控**表单中，在「开仓」按钮前显示 **预估盈亏比**。
+
+- **价格模式**：填完币种、方向、止损价、止盈价后，调用 `GET /api/order_defaults` 取标记价，按几何距离计算 RR。
+- **百分比模式**：填完币种、方向、止损%、止盈% 后拉快照校验币种，再显示 RR（`止盈% / 止损%`）。
+- **固定盈亏比模式**：填完币种、方向、止损价、盈亏比后取价校验几何合法，展示填写的盈亏比。
+
+与计仓方式无关：**以损定仓**（`POSITION_SIZING_MODE=risk`）与 **全仓杠杆**（`full_margin`）均显示同一预估。
+
+## 前端实现
+
+- 共享脚本：`static/manual_order_rr_preview.js`
+- 各所 `templates/index.html` 引入并在 `MANUAL_MIN_PLANNED_RR` 定义后执行：
+  ```js
+  ManualOrderRrPreview.wire({ minRr: MANUAL_MIN_PLANNED_RR });
+  ```
+- 展示元素：`#order-rr-preview`（开仓按钮左侧）
+- 颜色：≥ 最低要求为绿色，低于为红色，无效/取价失败为红色或灰色
+
+## 与提交校验
+
+提交时仍走原有 `calcClientRr` / `calcClientRrFromPct` 与 `rejectManualOrderRr`；预估仅用于下单前参考，不替代服务端风控。
+
+## 校验记录
+
+- `node --check static/manual_order_rr_preview.js`
+- `tests/test_manual_order_rr_preview.py`：RR 公式与四所 `calc_rr_ratio` 口径一致
