Update project configuration and dependencies - Added .mypy_cache and .cursor to .gitignore. - Changed asyncio_default_fixture_loop_scope and asyncio_default_test_loop_scope to "session" in pyproject.toml. - Updated e2e testing dependencies in requirements-dev.txt, replacing fakeredis and mongomock with pytest-httpserver. - Updated requirements.txt to use sientia_do instead of a specific git commit. - Modified sonar-project.properties to remove a file from coverage exclusions. - Enhanced E2E test fixtures in e2e/conftest.py for better container management. - Cleaned up e2e test files related to CoreScouter and PIWebAPIScouter workflows.
