/* test_settings_widgets.c — M7.2 设置页主列表迁 SDK 控件（宿主验证）。
 *
 * 复现 settings_page.c M7.2 SDK 路径所建控件集（meow_listview 虚拟化 vsource + section 段头 +
 * set_item_draw 自绘 + 行内真 meow_switch + 拖拽同布局 meow_slider），验证：
 *   P1 listview 虚拟化渲染：section 段头 + 开关/枚举/滑条/幂等行非背景像素；
 *   P2 meow_listview 命中：行号（含滚动换算 + 段头行 enabled=1 可命中）；
 *   P3 开关写回：行 tap → meow_settings_set_switch(key,!on) → settings.conf 键正确（读改写单键）；
 *   P4 滑条写回：track 映射 x→值 → meow_settings_set_int(key,v)（含息屏时间档位索引→秒）→ 键正确；
 *   P5 枚举写回：enum 选项 → meow_settings_set_enum(key,idx) → settings.conf 键值正确。
 * 写回全部走 meow_settings_set_*（单键读改写，勿整文件覆盖——音量存盘教训）+ meow_settings_save。
 *
 * 几何/控件创建与 settings_page.c「M7.2 SDK 路径」镜像（owner=哨兵 0x53，listview 用 set_vsource
 * + set_item_draw + set_item_h 68）。SMENU 行表取代表性子集（键/类型/min/max 与真表一致）。
