Add Comprehensive Unit Tests for PropertyRegistry

Overview

This PR implements a comprehensive unit test suite for the PropertyRegistry contract, ensuring robust test coverage for all core functionality, edge cases, and error handling scenarios.

Changes

Unit Test Suite (contracts/lib/src/tests.rs)

• Core functionality tests: Property registration, transfers, ownership verification, metadata handling
• Edge cases: Max values, zero values, empty strings, special characters, Unicode support
• Error handling: Unauthorized transfers, non-existent properties, invalid operations
• Performance tests: Bulk operations, large property lists, consistency under load
• Event verification: Tests ensure proper event emission for all state changes

CI/CD Integration

• Added unit test execution to main CI workflow
• Created dedicated test.yml workflow for unit tests
• Tests run automatically on push and pull requests
• Proper caching configuration for faster CI runs

🧹 Code Cleanup

• Removed unused imports from lib.rs and traits/lib.rs

Test Coverage

The test suite covers:

• ✅ Property registration and ID generation
• ✅ Property transfers and ownership updates
• ✅ Owner property lists management
• ✅ Metadata preservation and immutability
• ✅ Error conditions (unauthorized, not found, etc.)
• ✅ Edge cases (max values, empty strings, Unicode)
• ✅ Performance scenarios (bulk operations, large datasets)
• ✅ Event emission verification
• ✅ Timestamp accuracy

Testing

All tests pass locally and are integrated into the CI/CD pipeline. The test suite can be run with:

cd contracts/lib
cargo test --lib

This is how it looks:
