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
