fix(web): 系统设置 CRUD 修复 — version 乐观锁 + 语言字段映射 + JSON 显示

- API 层所有 Info/Request 接口添加 version 字段，update 函数传递 version
- delete 函数改为 client.delete(url, { data: { version } }) 发送 JSON body
- LanguageInfo.enabled → is_active，匹配后端 LanguageResp 字段名
- LanguageManager 编辑弹窗简化为只读详情（后端仅支持 is_active 切换）
- SystemSettings 设置值显示改用 JSON.stringify 而非 String()
- SystemSettings updateSetting 发送解析后的 JSON 对象而非字符串
