chore(CI): run new pattern tests in parallel (#1863)

## Summary
Refactors pattern tests integration tests to run as a separate parallel CI job instead of running sequentially within the main integration test job.

## Changes
- Created new dedicated `pattern-tests-integration-test` job in the GitHub Actions workflow
- Removed pattern tests step from the main `integration-test` job
- Updated pattern tests to run with `--parallel` flag for faster execution
