Extend Model entity with new `source` property which allow to refer adapter or container

[Pasichniuk]

Name and Version

0.6.1

What is the problem this feature will solve?

Currently, the Model entity lacks a dedicated property to explicitly reference its source, such as an adapter or container. This limitation makes it harder to establish clear associations and support referencial integrity in admin panel.

By introducing a source property, developers will be able to directly link a model to its adapter or container, improving readability and maintainability DIAL configuration.

What is the feature you are proposing to solve the problem?

Add a new source property to the Model entity to enable referencing either an adapter or a container. This enhancement will improve flexibility and streamline the process of associating modelds with their respective resources.

Acceptance Criteria

• The Model entity includes a new source property.
• The source property supports referencing both adapters and containers.
• Validation ensures that the source property is correctly populated and references valid resources.
• Documentation is updated to reflect the new property and provide clear usage guidelines.
• All tests pass, and no regressions are introduced.
