fix(webapp): regenerate the client after title became optional

PracticeAreaReviewArtifact.title is @nullable on the server and no longer
required in openapi.yaml, but the generated client still declared it as
always present. CI regenerates the client and fails on any diff, so the
two had to be brought back in step.
