fix: use proper test fixtures instead of local_session

- Replace local_session() calls with db_session fixture in tests
- Add @pytest.mark.asyncio decorators to async test functions
- Fix test_unpublish_shout.py to use proper test database setup
- Tests now use in-memory SQLite database with proper schema
- All test tables are created automatically via conftest.py fixtures
