feat: 补充微信小程序虚拟支付错误码枚举（268490001-268490024）

[Copilot]

微信小程序虚拟支付 API 新增了 22 个错误码（268490001~268490024），WxMaErrorMsgEnum 中缺少对应枚举值。

变更

• WxMaErrorMsgEnum.java：在枚举末尾新增 22 个虚拟支付错误码（官方文档中 268490010 与 268490017 不存在，跳过），并统一描述中的"账户"写法（帐户 → 账户）
• WxMaErrorMsgEnumTest.java（新增）：验证所有新增错误码可通过 findMsgByCode() 正确查找，以及缺失编号返回 null

CODE_268490001(268490001, "openid错误"),
CODE_268490002(268490002, "请求参数字段错误，具体看errmsg"),
CODE_268490003(268490003, "签名错误"),
// ... 共 22 个错误码
CODE_268490024(268490024, "广告金充值金额必须大于0"),

🤖 Augment PR Summary

Summary: This PR fills in missing WeChat Mini Program virtual payment error-code mappings (268490001–268490024) in WxMaErrorMsgEnum.

Changes:

• Added 22 new enum values for virtual payment errors (skipping undocumented 268490010 and 268490017).
• Added a TestNG test (WxMaErrorMsgEnumTest) to validate findMsgByCode() resolves the new codes and returns null for missing ones.

Technical Notes: Error messages are sourced from the official virtual payment API documentation and are verified via string equality in tests.

weixin-java-common/src/test/java/me/chanjar/weixin/common/error/WxMaErrorMsgEnumTest.java:14 This module’s surefire config runs TestNG via src/test/resources/testng.xml, and this new test class isn’t listed there, so it may never execute in CI. Consider adding it to the suite (or switching the suite to package scanning) so the new assertions actually run.

Severity: medium

该测试类的文件头 Javadoc 增加了 @author GitHub Copilot，但同包下已有测试类（如 WxErrorTest.java）通常不写作者信息；同时把工具名作为作者也容易造成归属信息不准确。建议删除该 author 行或改为实际贡献者/按项目惯例处理。

testFindMsgByCodeForExistingCode() 目前只断言返回值非空，无法验证返回的文案是否与枚举映射正确（例如误映射到其它错误码也会通过）。建议对一个稳定的已知错误码断言精确的期望消息，或直接复用/覆盖到本次新增的虚拟支付错误码用例中。
