feat: 重构数据库迁移架构，支持多数据库提供程序 (SQLite/SQLServer/PostgreSQL/MySQL)

Browse Source 
- 将迁移文件按数据库类型分目录存放 (Migrations/SQLite, MySQL, PostgreSQL, SqlServer)
- 新增各数据库提供程序的 DesignTimeDbContextFactory，支持 --provider 参数切换
- 新增 ProviderAppDataContexts，定义各数据库对应的 AppDataContext 子类
- DatabaseExtensions 增加 AddProviderAppDataContext 方法，按配置自动注册对应 DbContext
- 修正 MySQL 提供程序调用方式 (UseMySql -> UseMySQL)
- UserEntity 模型增加新字段
- 更新 add-migration.ps1
