Refactor monolith and system-test structure to Python

- Removed all Java-related files and configurations from the monolith directory, including Gradle build files, application classes, controllers, models, and resources.
- Deleted the settings.gradle and gradlew files from the monolith project.
- Updated the system-test directory to transition from Java to Python, including:
  - Renamed README.md to reflect Python usage and updated instructions for pytest.
  - Removed all Java test files and added Python test files for API and UI end-to-end and smoke tests.
  - Updated build.gradle and Gradle wrapper files to remove Java dependencies.
  - Added Python test structure with appropriate pytest markers for categorization.
