feat(ui/remo): 7003 总线新增 STATUS 身份查询与 GOTO 直达页（#69）

STATUS（命令 4）一帧回答"现在在哪个画面"：kind（MENU/PAGE/STANDBY）
+ 菜单路径/选中 + 页 id，布局契约与字节序见 ui_net_sink.h。由 uiTask
轮询驱动，同上下文读静态导航状态：零画面副作用、免锁、不发日志。
新增只读接口 ui_menu_get_nav_state / ui_content_page_current_desc。

GOTO（命令 5）按页 id 查生成表直开内容页，以 VIEW 权限进入（与
"已过查看密码"同档，不代输任何密码）。编译期门控
DTU_BENCH || UI_REMO_ALLOW_GOTO：产品构建恒拒（status=4），模拟器
构建默认开启便于无板验证；执行类页（clear/reset）固件侧同样拒绝
（status=2，与主机 EXEC_PAGE_IDS 同一事实源）；待机中拒绝（status=5），
由主机按键唤醒后再来。成功应答带回目标叶节点下标便于对账。

ui_sink 主机单测补导航侧链接假件 + 最小 lvgl 桩（仅本测试目录）。
产品构建 Keil 0 Error 0 Warning；ui_sink 单测 17/17。
