feat(device): 新增设备信息表 device + 上报接口

- 新建 device 设备表(设备/系统信息 + 网络/时区/模拟器/位置 + 关联用户 + 状态/时间戳), 以客户端 device_id 唯一标识;登录后回填 user_id,游客态可空 - 原 device 模型改名 device_liveness(实为无障碍存活表),腾出 device 名给新表并保持表名与实体名一致;同步更新 __init__ / repositories / admin queries / 文档引用 - 新增 POST /api/v1/device/report:软鉴权(带 JWT 绑用户、游客也收),按 device_id upsert; 设备信息非空才覆盖,位置 latitude/longitude 整字段覆盖含清空(以本次上报实际为准) - 新增 alembic migration bb47051068c8 建 device 表(裁掉 autogenerate 带出的无关表漂移) - 补 /device/report 端点与 upsert 单元测试 4 例
