ci: restructure Python test paths and add asyncio configuration

- Changed test paths from apps/coordinator-api and apps/blockchain-node to tests/archived_phase_tests and tests/cross_phase
- Removed --ignore flags for tests/production and test_confidential*.py files
- Added asyncio_mode = auto and asyncio_default_fixture_loop_scope = function to pytest.ini for better async test handling
