feat: 重构项目结构以支持新的用户界面和功能

- 更新 CMakeLists.txt，添加新的源文件和依赖项以支持应用程序结构 - 移除旧的 main.c 和 lvgl_demo_ui.c 文件，整合应用逻辑至 app_main.c - 新增 app/ui_handlers.c 和 app/ui_handlers.h，准备处理 UI 事件 - 引入 bsp/display.c 和 bsp/touch.c，配置显示和触摸功能 - 添加 services/wifi_manager.c，管理 Wi-Fi 连接 - 组织 UI 组件和资源，提升代码可维护性与可读性 - 更新相关头文件和配置，确保项目兼容性与功能完整性
