fix: update tests for current API structure and model changes

- Fix middleware fixtures: vendor_code instead of code, add owner_user_id to company
- Fix performance tests: MarketplaceProduct uses translations for title/description
- Fix security tests: use correct API endpoints (/api/v1/admin/*, /api/v1/vendor/*)
- Fix workflow tests: use actual admin API endpoints
- Fix background task tests: remove invalid vendor_name field, add language

Note: Many middleware integration tests still fail due to dynamic routes
being caught by the /{slug} catch-all route. These tests need further
refactoring to use /api/* prefixed routes.
