fix(supervisor): gate + display weekly-Sonnet, not weekly-Opus

On this claude.ai account the populated per-model weekly cap is Sonnet;
seven_day_opus is null (no separate Opus cap). So quota_available() now gates on
five_hour + seven_day + seven_day_sonnet (was seven_day_opus, which never bound),
and `status` prints weekly-Sonnet. The all-models seven_day cap remains the
backstop for Opus usage regardless. Matches the /operations display (#245).
