fix: 修复 Hedra 口型合成工具的 API 调用问题

- 修复前端和后端参数类型不匹配问题
- 在前端服务中添加 fileToBytes 方法，将 File 对象转换为字节数组
- 更新后端 HedraFileUploadRequest 结构，添加 purpose 字段
- 修复 Tauri 命令参数接收方式，使用 params 而不是 request
- 将 bowong_wait_for_task_completion 的模拟实现替换为真实的 API 调用
- 使用 wait_for_task_completion 方法实现真实的任务等待逻辑

现在 Hedra 工具应该能够正确调用后端 API 进行文件上传和任务处理
