diag(ui/wave): 枚举扫描诊断留痕第二组（临时构建，随根因修复收敛）

第一组埋点烧后开回放页串口零留痕（既无 FR 失败也无零条目
行），剩余唯一静默分支 = try 闸取锁失败直接返回/扫描成功但有条目
不打印/段头与窗口读取失败不打印。本组补齐：

- scan：每次尝试编号 #N；try 闸失败行带 vol_lock_get_stats 计数（消费方
  观测，不取锁，符合看门狗设计说明 §4.3 口径）；完成行改为无条件打印
  cnt/np/tt/ac（排除「成功但页面仍空」歧义）
- load_head / seg_win：try 闸、路径构造、开档 FR 码与读失败出口全部留痕

临时诊断构建，判性后随根因修复收敛到最小永久集。
/keil-build 0 错误 0 警告（Code +604 B，RAM 不变）。
