Refactor logging in integration tests and remove unused dependency

- Removed the unused 'jakarta.persistence:jakarta.persistence-api' dependency from build.gradle.
- Updated error logging in AirlineIntegrationTest, AirportIntegrationTest, and RouteIntegrationTest to use debug level for expected cleanup failures.

These changes streamline the project by eliminating unnecessary dependencies and improving logging clarity during test cleanup.
