LLMO-321: Add LLMO global sheet data endpoints and controller logic

[calvarezg]

Description

• Introduced new endpoints for retrieving LLMO global sheet data and data with specified sheet type in the OpenAPI specification.
• Implemented controller logic to handle requests to the new endpoints, including validation and data fetching from the external LLMO API.
• Added tests to ensure functionality and error handling for the new global sheet data retrieval feature.
