Run integration tests as separate CI job on Ubuntu only

- Add pytest marker for integration tests
- Configure automatic marking for tests/integration_tests/ folder via pytest hook
- Split CI workflow into two jobs: regular tests (all platforms) and integration tests (Ubuntu only)
- Integration tests can now be retried independently if they fail
