### Ⅰ. Describe what this PR did
This PR fixes flakiness in the `testToStringAndCycleDependency` unit test
within `StringUtilsTest`.
The flakiness was caused by **non-deterministic field ordering** returned by
**Java Reflection** when the `StringUtils.toString()` method processes
`CycleDependency` and `TestClass` objects. This led to `AssertionFailedError`
because the hardcoded expected string did not match the actual string when
fields were returned in an alternate order (e.g., `obj` then `s` instead of `s`
then `obj`, or vice-versa).
**No production code changes were made; this is a test-only change to
improve CI stability.**
### Ⅱ. Does this pull request fix one issue?
<!-- If that, add "fixes #xxx" below in the next line, for example, fixes
#97. -->
### Ⅲ. Why don't you add test cases (unit test/integration test)?
This PR specifically addresses the flakiness of an existing unit test
(`testToStringAndCycleDependency`) by making its assertions order-independent.
### Ⅳ. Describe how to verify it
To confirm the flakiness is resolved, run the affected test repeatedly using
a non-deterministic test runner such as
[nondex](https://github.com/TestingResearchIllinois/NonDex). Successful runs
across multiple attempts verify the fix:
```bash
mvn -pl common \
-am edu.illinois:nondex-maven-plugin:2.1.7:nondex \
-Dtest=org.apache.seata.common.util.StringUtilsTest#testToStringAndCycleDependency
\
-DnondexRuns=10 \
-DfailIfNoTests=false
```
### Ⅴ. Special notes for reviews
- No production code touched, and only modified one unit test case.
