Expose new GraphQL `event` field for `DesignType`

See merge request gitlab-org/gitlab-ee!15561

`event` corresponds with the mutation event of the `Design` in the
stateful `Version` (either the `Version` from the `atVersion` argument,
or the latest `Version` for the issue if no argument).

Prevent empty external authorization classification labels from overriding default label

Closes #66617

See merge request gitlab-org/gitlab-ce!32517

Most of the project templates bundled with GitLab have an empty string
set for `external_authorization_classification_label` in their
`project.json`. When imported this overrides the default label set on
the instance, causing the label to appear empty.

This change sets empty labels to nil during import, allowing the
default label to override it and be applied to the project.
