refactor(controller): 拆分回调函数到模块化文件并添加字符串列表访问器

- 将 callbacks.c 拆分为多个按功能分类的文件（callbacks_basic.c、callbacks_nav.c、callbacks_search.c、callbacks_io.c、callbacks_sys.c） - 新增 callbacks_internal.h 提供内部辅助函数声明，减少代码重复 - 在 string_ext 模块中添加 string_list_get 和 string_list_set 安全访问器函数 - 更新 CMakeLists.txt 和 ui_utils.c 以使用新的模块结构和访问器 - 重构旨在提高代码可维护性和可读性，便于后续功能扩展
