feat: 业务逻辑补全 — 佣金待审记录、C端订单重构、支付抽象、富友支付、卡设备状态联动

F-1: 佣金链断裂时创建 status=99 零额待审记录，新增修正接口 POST /commission-records/:id/resolve
F-4: C端订单查询从 Handler 迁移至 Service 层，移除 SkipPermissionCtx
J-1: 富友支付 JSAPI/MiniApp 预下单实现，回调补全签名验证
J-2: 平台钱包代购支持（buyerType 为空时使用资产所属代理钱包）
J-3: 套餐激活后自动更新卡/设备 status=3，最后套餐过期后更新 status=4
支付抽象: 引入 PaymentProvider 接口 + 微信/富友适配器，CreateOrder 支持多支付渠道
修复: 设备/IoT卡响应 DTO 移除 omitempty，空值字段返回 null 而非省略
