Add comprehensive unit tests for iOS and Android/KMM

This commit adds extensive unit test coverage for the entire application,
including iOS ViewModels, design system, and shared Kotlin Multiplatform code.

iOS Unit Tests (49 tests):
- LoginViewModelTests: Authentication state and validation tests
- ResidenceViewModelTests: Residence loading and state management
- TaskViewModelTests: Task operations (cancel, archive, mark progress)
- DocumentViewModelTests: Document/warranty CRUD operations
- ContractorViewModelTests: Contractor management and favorites
- DesignSystemTests: Color system, typography, spacing, radius, shadows

Shared KMM Unit Tests (26 tests):
- AuthViewModelTest: Login, register, verify email state initialization
- TaskViewModelTest: Task state management verification
- DocumentViewModelTest: Document state initialization tests
- ResidenceViewModelTest: Residence state management tests
- ContractorViewModelTest: Contractor state initialization tests

Test Infrastructure:
- Reorganized test files from iosAppUITests to MyCribTests
- All shared KMM tests passing successfully (./gradlew test)
- Tests focus on state initialization and core functionality
- Ready for CI/CD integration
