Add endpoint to retrieve stored object content

- Introduced `/1.0/doc-store/stored-object/{uuid}` endpoint to fetch the content of a stored object by UUID.
- Implemented access control using `StoredObjectRoleEnum::SEE` permission.
- Added OpenAPI specification for the new endpoint, including path parameter `uuid` and response codes `200` and `403`.
