- 新增 accounts 表与接口：POST /api/v1/accounts（用只读接口试拉流水校验，失败 ERR_BINANCE）、
GET /api/v1/accounts/{id}、POST .../verify、.../disable、.../enable；Secret 以 AES-256-GCM 加密存储，密钥由 API_AUTH_KEY 派生
- 订单增加 account_id（旧库自动补列，默认 default）；唯一金额按账号分配；Matcher 按账号各自轮询、缓存与匹配，
无待核销订单的账号不调币安接口；回填（claim）只在订单所属账号的流水里找
- 收银页按订单所属账号展示 UID / 收款链接 / 二维码；订单与回调体新增 account_id，订单响应新增 receive_link / receive_email
- Go / Python SDK 同步（AccountID、账号方法）；协议文档 §2.6；e2e 覆盖多账号隔离、回填、停用与默认账号保护
