Optimize IoTDBRestServiceIT errorInsertRecords

[HTHou]

This pull request refactors the errorInsertRecords integration test in IoTDBRestServiceIT.java to simplify its setup and improve maintainability. The test now uses the shared EnvFactory environment instead of creating a custom SimpleEnv cluster, and the verification logic has been streamlined.

Test refactoring and simplification:

• The errorInsertRecords test no longer creates and manages a separate SimpleEnv cluster; it now uses the shared EnvFactory environment for consistency and simplicity.
• The test logic is updated to iterate over all data nodes from EnvFactory, sending error insert requests to each and verifying the count of inserted records matches the number of data nodes. [1] [2]
• Removed the previous logic that stopped and restarted data nodes and checked for results after node failures, making the test less flaky and more focused.

Code cleanup:

• Unused imports related to SimpleEnv, consensus factories, and ResultSetMetaData have been removed for clarity. [1] [2] [3]
• The @Ignore annotation was removed, re-enabling the test.
• Replaced Thread.sleep(1000) with TimeUnit.SECONDS.sleep(1) for improved readability and consistency.
