Introduce a version restoration button and logic to track restored versions throughout the UI. Update download buttons to display action strings conditionally and implement toast notifications for version restoration.
Introduced a new normalizer for StoredObjectPointInTime and updated the StoredObjectVersionNormalizer to include point-in-time data when specified in the context. Added corresponding test cases to ensure the new normalization logic works correctly.
Added a new class StoredObjectVersionApiController in ChillDocGeneratorBundle which lists versions of a specified stored object. Corresponding unit test has been added as well. Made modifications in `StoredObject.php` to make the versions selectable. Also updated the API specifications to include a new GET route for retrieving versions.
