• Add "official" tests for Cursor Pagination
• Introducing test settings that can be used to install test-specific apps/models and set test-specific settings
• Cleanup tests, a.o. remove unused BDD test infrastructure
• Refactor to use Python's pathlib module for file-related tasks
• Upgrade to Django 4.2
• Rename directory askanna_backend to apps
