[MBL-19889][Teacher] Fix SpeedGrader grading status showing Graded when grade is null

Canvas sets workflow_state to "graded" even when only a comment is left
with no actual grade. The GraphQL-based SpeedGrader was using state ==
graded to determine the label, while the REST-based submission list
correctly checks grade != null. Added grade field to the GraphQL fragment
and gated SubmissionStateLabel.Graded on grade != null.
