feat(dbms): 增加数据库备份任务停止重启功能和MySQL支持

- 添加了备份任务停止和重启接口及实现
- 实现了对MySQL数据库的支持，包括数据库名配置
- 重构了数据库连接和备份操作的SPI架构
- 优化了备份文件删除逻辑，支持目录递归删除
- 增加了连接名称唯一性校验
- 完善了备份任务状态管理和错误处理机制
- 更新了数据库连接参数验证逻辑

 - 备份任务异步执行，只有实际文件生成成功后才会写入 `dbms_backup_file` 记录。
 - `JDBC_EXPORT` 当前会生成两类文件：
-  - 主数据文件：`*.csv`
+- MySQL `JDBC_EXPORT` 会按任务号创建独立备份目录，每张表独立 CSV，默认按 512MB 分片：

+  - 数据分片文件：`<table>_part001_yyyyMMdd_<taskNo>.csv`
+  - 元数据文件：`mysql_jdbc_export_metadata_yyyyMMdd_<taskNo>.json`
+- 备份任务支持停止和重新开始：
+  - `POST /database/backups/tasks/stop`
+  - `POST /database/backups/tasks/restart`
 - `JDBC_EXPORT` 恢复依赖元数据文件，不再允许缺少元数据直接发起恢复。
 - 删除备份文件时，会校验目标路径必须位于受管备份目录下，避免误删非备份文件。
