MeowOS f2786552d5 feat(launcher): 蓝牙/WiFi 独立子页面（安卓风）— 新增 subpage.c 统一脚手架(顶栏+分组列表+跟手滚动+左缘返回) + wifi_page.c(开关/当前连接详情/已保存/附近,BSSID去重+中文SSID) + bt_page.c(开关/已连接/已配对/附近扫描配对)；SMENU 网络组收敛为 2 入口行 (agent-178) 
launcher bd37c8b0→d10c0e8a; 改动文件 -Wall -Wextra 0 warning; 真机待验证: 蓝牙 pair/connect、开关联动、触摸几何
出入: 中文SSID/BSSID去重复用 net.c 既有实现; 模态复用 s_dd_modal(SDK 模态层未上收, 未改 SDK); s_net_open 旧分支留作死代码未删

/* subpage.c — MeowOS launcher 独立子页面（WiFi/蓝牙）统一脚手架（M2.76）。
*
* 安卓风子页骨架：顶栏（标题 + 返回 + 右上开关）+ 分组列表（组标题/行/开关/动作）
* + 滚动（跟手，方向沿用设置页 input.swipe_invert 语义）+ 左缘左滑返回 + 底部返回。
*
* 由页面（wifi_page.c / bt_page.c）通过 sub_page_t 提供：
* - title 顶栏标题
* - top_sw 顶栏开关（0=不显示；1=显示并回写当前值）
* - top_sw_set 开关切换（写设置 + 生效 + 触发重扫）
* - rows 填行（组标题/普通行/开关行/动作行），返回行数
* - act 点动作/开关行
* - detail 点普通行（如当前连接详情、网络/设备详情）
* - live 1=驻留时周期性(约2s)重扫行（蓝牙附近扫描等动态数据）
*
* 与设置页同主题（s_ui_theme，MD3 语义色，明暗自动）；局部刷新不整屏重绘；
* 模态弹窗交给 launcher 既有 s_dd_modal（点外关闭不穿透），本脚手架在回调返回后
* 彻底排空本页 tfd + 重置触摸基线（复刻 run_settings_page 后置排空，防穿透）。
*
* 物理键：电源=系统级语义（单击息屏/亮屏、长按电源菜单、8s 强关）、音量=系统音量、
* 播放=抓住——不再映射为返回（APPS §3.4.1 全局接管）。
