feat: 新增数据管理模块（区域管理）及修复前端已知问题

后端(bms-back):
- 新增区域管理完整后端：Domain/Mapper/Service/Controller + MyBatis XML
- 新增 RestTemplateConfig 配置类，用于第三方API调用
- 新增 countries.json 本地国家数据源（105个国家）
- RuoYiApplication 加 @EnableAsync 支持异步任务
- application-druid.yml 修复 Druid 连接池字符集配置(SET NAMES utf8mb4)
- logback.xml 日志路径改为 ${user.dir}/logs 避免沙箱写入受限
- pom.xml 增加 JVM 编码参数(-Dfile.encoding=UTF-8)
- 新增 sql/bms_region.sql 建表脚本+菜单权限

前端(bms-front):
- 新增区域管理页面(列表/编辑/状态切换/同步国家数据/导出)
- 新增同步日志功能(内嵌为区域管理弹窗，移除独立菜单)
- 新增 API 层: region.js / region-log.js
- 修复 BasicForm/index.vue 缺失 import FormControl 导致搜索栏控件不渲染
- 修复 user/role/region 三个页面 el-switch 初始化时弹 undefined 提示
