Investigate and update Pact versions with comprehensive contract testing implementation

[Copilot]

This PR addresses the investigation of Pact version updates and implements a comprehensive solution for consumer-driven contract testing in the repository.

Investigation Summary

After thoroughly analyzing the current dependency versions and available updates, I implemented a conservative update strategy that balances security, stability, and functionality:

• Spring Cloud: Updated from 2023.0.1 to 2023.0.6 (latest in current release train)
• Spring Cloud Contract: Automatically updated from 4.1.2 to 4.1.6 via dependency resolution
• Spring Boot: Maintained at 3.2.5 (compatible and stable)

Key Changes

Version Updates

The update follows a low-risk approach, staying within the same Spring Cloud release train while gaining important bug fixes and security patches. This avoids potential breaking changes from major version jumps while ensuring the project benefits from the latest stable improvements.

Contract Testing Implementation

Completed the previously disabled and incomplete contract testing setup:

• Provider Side: Added Spring Cloud Contract Maven plugin configuration with proper base test class
• Consumer Side: Enabled contract test with proper stub runner configuration
• Contract Definition: Implemented complete Groovy DSL contract specification
• Field Mapping: Resolved data model inconsistency between consumer and provider (standardized on zipCode)

Technical Demonstration

The implementation now provides a fully functional CDC testing pipeline:

Contract.make {
    description "should return a customer with invoice address"
    request {
        method 'GET'
        url '/customers/cust123'
        headers { accept(applicationJson()) }
    }
    response {
        status OK()
        headers { contentType(applicationJson()) }
        body([
            customerId: "cust123",
            invoiceAddress: [zipCode: "1234AB", houseNumber: "123"]
        ])
    }
}

Validation Results

• ✅ All contract tests pass on both provider and consumer sides
• ✅ Project compiles and builds successfully with updated versions
• ✅ Spring Cloud Contract functionality fully operational
• ✅ Stub generation and consumption working correctly

Documentation

Added comprehensive investigation report (PACT_VERSION_INVESTIGATION.md) detailing:

• Current version analysis and compatibility assessment
• Available update options with risk/benefit analysis
• Future upgrade recommendations and planning guidance
• Security and maintenance considerations

The investigation confirms that while the previous versions were functional, this conservative update provides optimal benefits without introducing unnecessary risk. The project is now well-positioned for future updates and has a fully operational contract testing workflow.

Fixes #3.
