Fix 422 on grading save when no AI comment log exists

update_final_comment/2 returned {:error, :not_found} whenever an
answer had no AI-comment log row (i.e. the grader never used the
AI-assisted commenting feature), which is the case for the vast
majority of submissions. The controller treated any {:error, _} as a
changeset failure and returned 422, so saving grading changes from
the Grading tab failed with "Error while communicating with backend:
422" on essentially every submission, since the frontend calls
save-final-comment on every grading save regardless of whether AI
comments were ever generated.

Treat a missing AI comment log as a no-op success instead of an
error, since there's nothing to attach the final comment to.

Fixes source-academy/frontend#4233
