Remove otvoreno field references from all test files

- Updated ui-features.test.ts to remove otvoreno field expectations
- Updated api-integration.test.ts to remove otvoreno from test data
- Updated data-consistency.test.ts to remove otvoreno from structure definitions
- Updated filament-crud.test.ts to remove otvoreno from CRUD operations
- Updated quantity calculations to only use refill and vakuum fields

All tests pass after these changes.
