♻️ refactor(payment): 重构支付集成测试

- 统一使用微信支付SDK模拟替代手动mock
- 修复测试中使用固定externalOrderId导致的冲突问题
- 优化测试数据处理，使用数据库中保存的outTradeNo
- 调整测试用例以匹配最新的业务逻辑

✨ feat(payment): 完善支付回调测试

- 添加对无效JSON数据格式的测试覆盖
- 修复回调请求头设置，确保content-type正确
- 优化测试断言，验证更多支付参数字段

🐛 fix(payment): 修复支付状态检查错误提示

- 更正支付状态错误提示信息，使其更准确
- 修复测试中订单ID参数名不一致问题(externalOrderId→orderId)
- 调整无效回调数据测试的预期状态码
