feat: add optional inventory package association to service items and implement audit logging

- Added `inventory_package_uuid` and `inventory_package_title` fields to the `ServiceItem` interface.
- Updated API documentation to reflect new fields in service item responses.
- Implemented methods in `ClinicServiceController` to handle inventory package associations.
- Created `ServiceItemAuditLog` entity and repository for tracking changes to service items.
- Added functionality to log changes to service items, including inventory package associations.
- Implemented tests for attaching/detaching inventory packages and auditing changes.
- Created database migrations for new fields and audit log table.
