Refactor logging to use debugPrint for better performance in debug mode

- Updated all print statements in services and widgets to use debugPrint.
- This change improves logging performance and ensures that debug messages are only shown in debug builds.
- Removed unnecessary transitive dependencies from pubspec.lock.
- Cleaned up pubspec.yaml by removing integration_test from dev_dependencies.
