已完成迁移验收和清理。

删除全部 Node.js 后端、.mjs 测试、辅助脚本、package*.json、node_modules 和迁移对照工具。
浏览器前端保留并迁入 [Eis.Web/wwwroot](C:/Users/BI/Documents/EIS-dotnet/src/Eis.Web/wwwroot/index.html)，统一改为 .js 模块。
修复一个隐藏遗漏：.NET 仍依赖 schema.mjs，且 MySQL 结构解析可能被转义反引号截断。现已改为原生 [SQLite SQL](C:/Users/BI/Documents/EIS-dotnet/src/Eis.Infrastructure/Data/Schema.sqlite.sql) 和 [MySQL SQL](C:/Users/BI/Documents/EIS-dotnet/src/Eis.Infrastructure/Data/Schema.mysql.sql) 资源。
更新了 [DatabaseInitializer.cs](C:/Users/BI/Documents/EIS-dotnet/src/Eis.Infrastructure/Data/DatabaseInitializer.cs)、项目配置、README 和迁移文档。
data 目录和现有数据库未修改；测试仅使用系统临时 SQLite 数据库。
