SIENTIAPDE-1646

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.
