- 合并为单一初始全量迁移，覆盖 users/user_devices/user_points/point_batches/point_transactions/point_recharge_orders - 去掉所有 ForeignKey 约束（业务层软删除，不依赖数据库级联） - 去掉不必要的索引，仅保留 Unique 约束自带索引 - 修复 mjk_users.id 为 UUID 类型（非 String(36)） - 修复 user_device.last_active_at 时区类型一致性（添加 timezone=True）

用户积分汇总表
|
|
==============
|
|
|
|
记录用户当前可用积分及累计统计。
|
|
|
|
设计说明：
|
|
- 余额是实时计算的聚合值，查询时不需要 JOIN batches
|
|
- 每次充值/消费/过期都同步更新此表
|
|
- SELECT ... FOR UPDATE 锁定此表行，防止并发超扣
