Transfer_liquid (#176)

* change 9320 desk row number to 4

* Updated 9320 host address

* Updated 9320 host address

* Add **kwargs in classes: PRCXI9300Deck and PRCXI9300Container

* Removed all sample_id in prcxi_9320.json to avoid KeyError

* 9320 machine testing settings

* Typo

* Typo in base_device_node.py

* Enhance liquid handling functionality by adding support for multiple transfer modes (one-to-many, one-to-one, many-to-one) and improving parameter validation. Default channel usage is set when not specified. Adjusted mixing logic to ensure it only occurs when valid conditions are met. Updated documentation for clarity.

+# HTTP API 指南
+
+本文档介绍如何通过 HTTP API 与 Uni-Lab-OS 进行交互，包括查询设备、提交任务和获取结果。
+
+## 概述
+
+Uni-Lab-OS 提供 RESTful HTTP API，允许外部系统通过标准 HTTP 请求控制实验室设备。API 基于 FastAPI 构建，默认运行在 `http://localhost:8002`。
+
+### 基础信息
+
+- **Base URL**: `http://localhost:8002/api/v1`
+- **Content-Type**: `application/json`
+- **响应格式**: JSON
+
+### 通用响应结构
+
+```json
+{
+    "code": 0,
+    "data": { ... },
+    "message": "success"
+}
+```
+
+| 字段      | 类型   | 说明               |
+| --------- | ------ | ------------------ |
+| `code`    | int    | 状态码，0 表示成功 |
+| `data`    | object | 响应数据           |
+| `message` | string | 响应消息           |
+
+## 快速开始
+
+以下是一个完整的工作流示例：查询设备 → 获取动作 → 提交任务 → 获取结果。
+
+### 步骤 1: 获取在线设备
+
+```bash
+curl -X GET "http://localhost:8002/api/v1/online-devices"
+```
+
+**响应示例**:
+
+```json
+{
+  "code": 0,
+  "data": {
+    "online_devices": {
+      "host_node": {
+        "device_key": "/host_node",
+        "namespace": "",
+        "machine_name": "本地",
+        "uuid": "xxx-xxx-xxx",
+        "node_name": "host_node"
+      }
+    },
+    "total_count": 1,
+    "timestamp": 1732612345.123
+  },
+  "message": "success"
+}
+```
+
+### 步骤 2: 获取设备可用动作
+
+```bash
+curl -X GET "http://localhost:8002/api/v1/devices/host_node/actions"
+```
+
+**响应示例**:
+
+```json
+{
+  "code": 0,
+  "data": {
+    "device_id": "host_node",
+    "actions": {
+      "test_latency": {

+      }
+    },
+    "action_count": 5
+  },
+  "message": "success"
+}
+```
+
+**动作状态字段说明**:

+| ---------------------------------------------------------- | ---- | ---------------------- |
+| `/api/v1/online-devices`                                   | GET  | 获取在线设备列表       |
+| `/api/v1/devices`                                          | GET  | 获取设备配置           |
+| `/api/v1/devices/{device_id}/actions`                      | GET  | 获取指定设备的可用动作 |
+| `/api/v1/devices/{device_id}/actions/{action_name}/schema` | GET  | 获取动作参数 Schema    |
+| `/api/v1/actions`                                          | GET  | 获取所有设备的可用动作 |
+
+### 任务相关
+
+| 端点                          | 方法 | 说明               |
+| ----------------------------- | ---- | ------------------ |
+| `/api/v1/job/add`             | POST | 提交新任务         |
+| `/api/v1/job/{job_id}/status` | GET  | 查询任务状态和结果 |
+
+### 资源相关
+
+| 端点                | 方法 | 说明         |
+| ------------------- | ---- | ------------ |
+| `/api/v1/resources` | GET  | 获取资源列表 |
+
+## 常见动作示例
+
+### test_latency - 延迟测试
+
+测试系统延迟，无需参数。
+
+```bash
+curl -X POST "http://localhost:8002/api/v1/job/add" \
+  -H "Content-Type: application/json" \
+  -d '{"device_id":"host_node","action":"test_latency","action_args":{}}'
+```
+
+### create_resource - 创建资源
+
+在设备上创建新资源。
+
+```bash
+curl -X POST "http://localhost:8002/api/v1/job/add" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "device_id": "host_node",
+    "action": "create_resource",
+    "action_args": {
+        "res_id": "my_plate",
+        "device_id": "host_node",
+        "class_name": "Plate",
+        "parent": "deck",
+        "bind_locations": {"x": 0, "y": 0, "z": 0}
+    }
+}'
+```
+
+## 错误处理
+
+### 设备繁忙
+
+当设备正在执行其他任务时，提交新任务会返回 `status: 6`（ABORTED）：
+
+```json
+{
+  "code": 0,
+  "data": {
+    "jobId": "xxx",
+    "status": 6,
+    "result": {}
+  },
+  "message": "success"
+}
+```
+
+此时应等待当前任务完成后重试，或使用 `/devices/{device_id}/actions` 检查动作的 `is_busy` 状态。
+
+### 参数错误
+
+```json
+{
+    "code": 2002,
+    "data": { ... },
+    "message": "device_id is required"
+}
+```
+
+## 轮询策略
+
+推荐的任务状态轮询策略：
+
+```python
+import requests
+import time
+
+def wait_for_job(job_id, timeout=60, interval=0.5):
+    """等待任务完成并返回结果"""
+    start_time = time.time()
+
+    while time.time() - start_time < timeout:
+        response = requests.get(f"http://localhost:8002/api/v1/job/{job_id}/status")
+        data = response.json()["data"]
+
+        status = data["status"]
+        if status in (4, 5, 6):  # SUCCEEDED, CANCELED, ABORTED
+            return data
+
+        time.sleep(interval)
+
+    raise TimeoutError(f"Job {job_id} did not complete within {timeout} seconds")
+
+# 使用示例
+response = requests.post(
+    "http://localhost:8002/api/v1/job/add",
+    json={"device_id": "host_node", "action": "test_latency", "action_args": {}}
+)
+job_id = response.json()["data"]["jobId"]
+result = wait_for_job(job_id)
+print(result)
+```
