/* bg_page.c — 批③ 后台管理页（桌面顶栏居右按钮进入）。
|
||
*
|
||
* 容器：sub_page_t 脚手架（subpage.c，与 wifi_page/bt_page 同款）。顶栏＝meow_topappbar：
|
||
* 返回箭头 + 标题「后台管理」+ **顶栏标题栏右侧「一键清除后台」按钮**（sub_page_t.top_action，
|
||
* act＝bgm_top_action → bgmgr_kill_all，**不杀框架/当前前台/非后台**，经 bgmgr_can_kill 门控）。
|
||
* 列表（live=1 约 2s 重扫，实时增删）：
|
||
* - 每后台 App 一行 SUB_ROW：label=名字，sub=「CPU x% · yMB · 状态」，**行最右一个「杀」按钮**
|
||
* （sub_page_t.row_draw 行自绘 + row_tap 自定义命中：命中按钮区＝kill 该 App；行体不响应）。
|
||
* - 行=MD3 圆角卡（meow_gfx_fill_round r=12 surfaceContainer；卡在行高内上下对称内缩
|
||
* BGM_CARD_GAP/2，行中心=卡中心，相邻卡 8px 外距——与主界面列表/ ncm 歌单同手法）。
|
||
* - 空态「无后台 App」。
|
||
* 数据源＝amsd FG/BG 注册表（后台常驻集＝launcher meow_bg 表，EV BG/FG 上报进 amsd）+ 每进程
|
||
* pcpu/rss（meow_svc_perf 同源 /proc 聚合，本页在 launcher 内同口径取）。
|
||
*
|
||
* 按钮化（相对 agent-425 的「点行 kill + 顶置清除动作行」）：
|
||
* - kill：改「点整行」为「行最右独立杀按钮」——行自绘（bgm_row_draw）+ 自定义命中（bgm_row_tap），
|
||
* 命中几何＝bgm_btn_rect（行右 46×34 圆角按钮）；行体其它区域 point 回 0（不杀）。
|
||
* - 清：删顶置「一键清除后台」SUB_ACT 动作行，改为顶栏标题栏右侧 action 按钮（top_action）。
