Unicorn approvals

Summary

Changes

This pull request refactors the Unicorn Properties service into Unicorn Approvals service, updating the namespace and service naming throughout the codebase. The main changes include:

• Service Rename: Renamed Unicorn.Properties to Unicorn.Approvals throughout the codebase
• Namespace Updates: Updated all references from UnicornPropertiesNamespace to UnicornApprovalsNamespace
• Event Bus References: Updated all event bus references from UnicornPropertiesEventBus to UnicornApprovalsEventBus
• Documentation Updates: Updated README files and documentation to reflect the new service name

User experience

Before: The service was named "Unicorn Properties" which could be confusing as it handled approval workflows rather than property management directly.

After: The service is now named "Unicorn Approvals" which more accurately reflects its purpose of handling approval workflows for contracts and properties. This provides better clarity for developers and users about the service's actual functionality.
