refactor: 改造订单和资产充值 Service，支持动态支付配置

- order/service.go: 注入 wechatConfigService，CreateH5Order/CreateAdminOrder 下单时查询 active 配置并记录 payment_config_id；无配置时拒绝第三方支付；WechatPayJSAPI/WechatPayH5/FuiouPayJSAPI/FuiouPayMiniApp 添加 TODO 留桩
- recharge/service.go: Create 方法记录 payment_config_id，HandlePaymentCallback 留桩
