refactor(base): 重构基础组件和数据库访问层

- 修复 BaseActivity 中 rightIconActon 方法名拼写错误
- 重命名 appViewModel 为 dbViewModel 以统一数据库访问实例
- 优化 BaseApp 中的共享偏好设置获取逻辑
- 移除 GlobalData 中硬编码的应用ID和SDK密钥
- 重命名 NetworkUtils 为 NetworkUtil 并增强网络连接检测
- 重构 RemoteRepository 中的API调用方法结构
- 在多个Activity和Fragment中统一使用dbViewModel替代appViewModel
- 优化食品列表合并烹饪中条目的逻辑处理
- 调整文件上传时的媒体类型定义
- 清理注释和代码结构以提高可维护性
