chore: 完成项目整体打包与配置更新

1. 更新所有服务Dockerfile，切换到eclipse-temurin:17-jre-alpine镜像并调整服务端口 2. 配置前端项目基础路径与nginx代理 3. 新增数据库初始化编码设置与测试依赖 4. 添加部分服务的Servlet编码配置与JWT/LLM密钥配置 5. 完善话术实体类校验注解与Mapper接口 6. 新增密码生成工具类与部分测试文件配置

+# 企微会话存档 SDK 对接指南
+
+## 一、SDK 下载
+
+### 官方下载地址
+- 企微开发者中心：https://developer.work.weixin.qq.com/document/path/91774
+- 下载页面：「获取会话内容」→ SDK 下载
+
+### 下载版本选择
+| 环境 | 推荐版本 | 说明 |
+|------|---------|------|
+| Windows x64 | SDK v3.0 (OpenSSL 3.0) | 2025-02-13 更新 |
+| Linux x64 | SDK v3.0 (OpenSSL 3.0) | 2025-02-13 更新 |
+
+### Windows SDK 文件清单
+解压后 `financeWinSdk/java_sdk/WeWorkFinanceSdk/` 目录下包含：
+
+| 文件 | 说明 |
+|------|------|
+| `WeWorkFinanceSdk.dll` | 主 SDK 动态库 |
+| `libcrypto-3-x64.dll` | OpenSSL 3.0 依赖 |
+| `libssl-3-x64.dll` | OpenSSL 3.0 依赖 |
+| `libcurl-x64.dll` | libcurl HTTP 依赖 |
+| `Finance.java` | 官方 JNI 封装（本项目使用 JNA，无需此文件） |
+
+## 二、SDK 放置
+
+### Windows 环境
+
+将上述 4 个 DLL 文件放到项目目录：
+
+```
+backend/archive-service/
+└── sdk/                      <-- 新建此目录
+    ├── WeWorkFinanceSdk.dll
+    ├── libcrypto-3-x64.dll
+    ├── libssl-3-x64.dll
+    └── libcurl-x64.dll
+```
+
+### Linux 环境
+
+```bash
+# 将 libWeWorkFinanceSdk_Java.so 重命名并放到系统库路径
+sudo cp libWeWorkFinanceSdk_Java.so /usr/lib/libWeWorkFinanceSdk.so
+sudo ldconfig
+
+# 或者放到项目目录并通过环境变量指定
+mkdir -p backend/archive-service/sdk
+cp libWeWorkFinanceSdk_Java.so backend/archive-service/sdk/libWeWorkFinanceSdk.so
+```
+
+## 三、配置参数
+
+### 环境变量方式（推荐）
+
+```bash
+# 企微会话存档 Secret
+export WECOM_ARCHIVE_SECRET="your-archive-secret"
+
+# RSA 私钥（PKCS#1 格式，Base64 编码）
+export WECOM_ARCHIVE_RSA_KEY="-----BEGIN RSA PRIVATE KEY-----\nMIIE...\n-----END RSA PRIVATE KEY-----"
+
+# 回调验证 Token（企微后台配置的 Token）
+export WECOM_ARCHIVE_CALLBACK_TOKEN="your-callback-token"
+
+# SDK 路径（指向存放 DLL/SO 的目录）
+export WECOM_ARCHIVE_SDK_PATH="D:\www\agent_9art\backend\archive-service\sdk"
+
+# Mock 模式（开发测试用，无真实 SDK 时设为 true）
+export WECOM_ARCHIVE_MOCK=false
+```
+
+### application.yml 配置项
+
+```yaml
+wecom:
+  archive:
+    corp-id: wwd483c2fba24ae30a          # 企业微信 CorpID
+    secret: ${WECOM_ARCHIVE_SECRET:}      # 会话存档 Secret
+    rsa-private-key: ${WECOM_ARCHIVE_RSA_KEY:}           # RSA 私钥
+    callback-token: ${WECOM_ARCHIVE_CALLBACK_TOKEN:}     # 回调 Token
+    sdk-path: ${WECOM_ARCHIVE_SDK_PATH:}                 # SDK 目录路径
+    mock-mode: ${WECOM_ARCHIVE_MOCK:false}               # Mock 模式开关
+```
+
+## 四、参数获取方式
+
+### 1. CorpID
+企微管理后台 → 「我的企业」→ 「企业ID」
+
+### 2. 会话存档 Secret
+企微管理后台 → 「管理工具」→ 「会话内容存档」→ 查看 Secret
+
+### 3. RSA 密钥对
+```bash
+# 生成 RSA 私钥（PKCS#1 格式）
+openssl genrsa -out private_key.pem 2048
+
+# 提取公钥
+openssl rsa -in private_key.pem -pubout -out public_key.pem
+
+# 将公钥配置到企微后台
+# 将私钥内容配置到 WECOM_ARCHIVE_RSA_KEY 环境变量
+```
+
+### 4. 回调 Token
+企微后台配置接收消息时设置，用于验证回调请求签名。
+
+## 五、Mock 模式（开发/测试）
+
+当没有真实企微 SDK 或不想连接企微服务器时，启用 Mock 模式：
+
+```bash
+export WECOM_ARCHIVE_MOCK=true
+```
+
+Mock 模式下：
+- 跳过 SDK 初始化，不会报错
+- `pullMessages()` 返回 10 条模拟会话消息
+- 完整的 `saveAndNotify()` 链路正常工作（入库 + MQ + Redis）
+- 数据看板可以展示存档统计
+
+**测试接口：**
+```bash
+# 手动触发拉取（Mock 模式下返回模拟数据）
+curl -X POST "http://localhost:8082/api/v1/archive/pull" \
+  -d "seq=0&limit=10"
+```
+
+## 六、验证对接成功
+
+### 1. 启动服务时日志
+```
+# 真实 SDK 模式
+企微存档SDK初始化成功
+
+# Mock 模式
+企微存档Mock模式已启用，跳过SDK初始化
+```
+
+### 2. 手动拉取测试
+```bash
+curl -X POST "http://localhost:8082/api/v1/archive/pull" \
+  -d "seq=0&limit=5"
+```
+
+### 3. 回调测试（需配置可信域名）
+企微后台配置回调 URL 为：
+```
+https://your-domain/api/v1/archive/callback
+```
+
+## 七、常见问题
+
+### Q1: 启动报错 `UnsatisfiedLinkError: Unable to load library 'WeWorkFinanceSdk'`
+- 检查 `WECOM_ARCHIVE_SDK_PATH` 是否指向正确的 DLL 目录
+- 确认 DLL 文件名正确（Windows 为 `WeWorkFinanceSdk.dll`）
+- 确认依赖库（libcrypto/libssl/libcurl）也在同一目录
+
+### Q2: SDK 初始化返回非 0
+- 检查 `corp-id` 和 `secret` 是否正确
+- 确认企业已开通「会话内容存档」功能
+
+### Q3: 回调签名验证失败
+- 检查 `callback-token` 是否与企微后台配置一致
+- 确认回调 URL 没有被中间件修改参数
+
+### Q4: 数据库查询不到存档消息
+- 检查 `archive_messages` 表是否有 `deleted` 字段（逻辑删除）
+- MyBatis-Plus 全局配置 `logic-delete-field: deleted`
