重构数据库备份与恢复模块 (#80)

* fix: 保存 LastResult 时截断字符串过长部分，以避免数据库报错

* refactor: 新增 entity.DbTaskBase 和 persistence.dbTaskBase, 用于实现数据库备份和恢复任务处理相关部分

* fix: aeskey变更后，解密密码出现数组越界访问错误

* fix: 时间属性为零值时，保存到 mysql 数据库报错

* refactor db.infrastructure.service.scheduler

* feat: 实现立即备份功能

* refactor db.infrastructure.service.db_instance

* refactor: 从数据库中获取数据库备份目录、mysql文件路径等配置信息

* fix: 数据库备份和恢复问题

* fix: 修改 .gitignore 文件，忽略数据库备份目录和数据库程序目录
