Update warranty status to use backend calculation and add comprehensive tests

Client-Side Changes:
- Add WarrantyStatus data class to Document model for backend-calculated status
- Update WarrantyCard to display backend status (statusText, statusColor) with client fallback
- Fix document list refresh: call loadDocuments() after create/update operations

Testing:
- Add ComprehensiveDocumentWarrantyTests with 25+ XCUITest cases
- Test document creation, update, delete, image upload
- Test warranty-specific fields and property selection
- Test both general documents and warranties
- Includes helper methods for form interaction and cleanup

Other:
- Update ApiConfig and PushNotificationManager
