UI 内容页框架加实时页自动刷新机制（交流量页启用，300ms）

- ui_content_page：描述符尾部追加 auto_ms/auto_seq 可选字段（缺省=0/NULL=
  旧行为逐位不变）；页打开期间框架持一只 lv_timer，仅当发布序号变过才整页
  失效（零空转失效），关页即销；新 API ui_content_page_auto_poll
- ui_page_ac.c：.auto_ms=300（≥200ms 发布节拍、避 400=2×200 锁相、300=
  15×20ms LVGL 整刷周期；最坏屏上滞后 500ms；完整取值账目在代码注释）
- simulator：rt 帧装配收口 sim_fill_rt_frame（n=0 冻结帧保 74 张黄金逐字节
  一致，n≥1 确定性斜坡）；新增 --rtlive 两态自检 + 窗口模式 200ms 节拍发布；
  check_content_pages.py 增 [rtlive] 零按键 A≠B 落屏断言
- docs/UI设计：供给说明新增 §5.5 自动刷新口径；内容页架构 §3.1/§四/§九 同步
  （并修正 s_open 判定旧描述）
- 台账：Keil 构建后按固定顺序回填（Code=256,588 / RW_IRAM1 +8B / UI +8B）

验证：模拟器 0错0警；菜单 8 状态 + 内容页 74 张 + rtlive（A≠B 30 字节）PASS
（lead 独立复跑 RC=0）；Keil 0错0警；mem-budget --gate / mem-numbers --scan 绿。
