### Ⅰ. Describe what this PR did
This PR resolves flakiness in the `testGetPrimaryKeyOnlyName` unit test in
`rm-datasource/src/test/java/org/apache/seata/rm/datasource/sql/struct/TableMetaTest.java`.
The test was failing intermittently when multiple primary keys were defined
(`id`, `userCode`). This was caused by the test relying on a fixed, hardcoded
order for the list of primary key names, while the method's underlying
collection (`TableMeta.getAllIndexes()`) does not guarantee a fixed iteration
order.
The fix ensures a stable, order-independent comparison by sorting both the
actual and expected lists of primary key names before assertion.
**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 existing unit tests
### Ⅳ. Describe how to verify it
To confirm the flakiness is resolved, run the affected tests repeatedly
using a non-deterministic test runner such as
[nondex](https://github.com/TestingResearchIllinois/NonDex) to verify
stability. Successful runs across multiple attempts verify the fix.
For example, run the following command:
```bash
mvn -pl rm-datasource \
-am edu.illinois:nondex-maven-plugin:2.1.7:nondex \
-Dtest=org.apache.seata.rm.datasource.sql.struct.TableMetaTest#testGetPrimaryKeyOnlyName
\
-DnondexRuns=10 \
-DfailIfNoTests=false
```
### Ⅴ. Special notes for reviews
- Test-only change in the `rm-datasource` module.
- No production code modified.
