Add happy path examples and Links to OpenAPI documentation

[davideme]

Enhance the OpenAPI specification file at @davideme/lamp-control-api-reference/files/docs/api/openapi.yaml by adding:

1. Happy Path Examples: Provide positive, successful API interaction examples for all relevant endpoints to improve clarity for API consumers.
2. Links: Implement OpenAPI 3.0 Links to document relationships between operations, enabling better navigation and understanding of workflow.

This will improve the developer experience and help users understand how to use the API more effectively.
