feat(device): 无障碍保护存活心跳检测 + 掉线终端告警

- 新增 device 表 + /api/v1/device/{register,heartbeat} + 迁移 device_table
- heartbeat_monitor_worker 周期扫描心跳超时(App 被杀/无障碍停)→ 服务器终端打印告警
  (推送本期未接,先用 logger 终端打印代替真实通知;integrations/jpush.py 已备,后续直接替换)
- config / .env.example 增 JPUSH_* / HEARTBEAT_*
- 见 spec(仓库外 e:\codes\spec\accessibility-liveness-push.md)

注:本提交同时快照了并行 session 未提交的 coupon_state 改动 + 相关 migration
(与本功能同迁移链耦合,无法单独拆分,经确认一并提交)。

 ## 说明

-- 排序:`sort_by`(id/created_at)× `sort_order`(asc/desc),恒以 `id` 同向兜底次序。
-- `status` / `user_id` 精确匹配、`content` 模糊、`created_from`/`created_to` 时间范围,均可叠加。
