Avoid login lock for pipe auth retry

[Caideyipi]

Summary

• slow down pipe retry intervals for authentication failures to avoid triggering the default login lock window
• preserve receiver auth status codes in sync and legacy handshake error messages
• add unit coverage for auth failure detection and retry interval behavior

Tests

• mvn spotless:apply -pl iotdb-core/node-commons
• mvn test -pl iotdb-core/node-commons -Dtest=PipeSleepIntervalTest
• git diff --check

Notes

• mvn -pl iotdb-core/datanode -DskipTests compile reached javac but failed in this environment with Java heap space / pagefile memory errors.
