test: update service tests for fixture and API changes

Updates to work with refactored fixtures (no expunge):
- Re-query entities when modifying state in tests
- Remove assertions on expunged object properties

Auth service tests:
- Update to use email_or_username field instead of username

Admin service tests:
- Fix statistics test to use stats_service module
- Remove vendor_name filter test (field removed)
- Update import job assertions

Inventory/Marketplace/Stats/Vendor service tests:
- Refactor to work with attached session objects
- Update assertions for changed response formats
- Improve test isolation and cleanup
