This commit removes nullable Uuid properties for consistency, transitions the Correction entity to QuizCandidate with associated migrations, refactors queries and repositories, adjusts related routes and controllers to use the new entity, updates front-end assets for elimination workflows, and standardizes route requirements and naming conventions.
