Main stubbed ai_score/recommendation as None in the candidate-profile payload;
fill them from the scoring engine's candidates table, joined by inbox message
(one batched query for the list, assigned-job-preferred for the detail). The
detail payload also gains matched/missing keywords, the critique, and which job
the score was against.
Frontend: TalentPool cards and the profile hero prefer the real score over the
seed placeholder, and the profile grows a Score-with-ATS button (shown when the
candidate has an assigned job and an inbox message) that runs the existing
score_inbox pipeline and repaints via the detail refetch.
