Add ResultViewController for output result retrieval

Introduce ResultViewController with endpoints to fetch output results by query, for fake/test profiles, and by action ID. Supports returning full, header, or body parts of results via a new ViewResultType enum. Utilizes MediatR and configuration injection for flexible and testable result access. Includes XML docs for improved API clarity.
