zhangtao 60fe97afc3 refactor(gen): 重构代码生成模块,实现权限认证和分页支持
- 重构GenTableDao和GenTableColumnDao,继承CRUDBase,添加权限鉴权支持
- 优化分页逻辑,支持非分页时返回完整结果集
- 调整查询条件,支持大小写不敏感模糊查询和时间范围过滤
- 统一接口响应格式,返回SuccessResponse或ErrorResponse
- 替换旧的依赖和注解,改用新的认证和日志中间件
- 文档README.en.md和README.md内容格式及示例完善与优化
- alembic/env.py中数据库URL配置优化,增加异常检测保障环境配置正确
- 代码生成控制器genController新增代码批量生成下载流和本地生成文件覆盖检测
- 删除或更新废弃代码,清理无用导入,提升项目整体代码质量和可维护性
