- Remove items_count annotate conflict with @property
- Add purchase_cost to EquipmentListSerializer fields
- Add requestor field to ProcurementRequestCreateSerializer response
- Fix test_list_budgets_regular_user - expect 403 not 200
- Add settings_test.py with InMemoryChannelLayer for tests
- Update pytest.ini to use settings_test

Result: 38/41 tests PASSED (was 26/41)
