Portfolio rollup across all your apps (Agency plan)

The whole portfolio's health in one call: per-app KPIs (visibility + matched-cohort 7-day delta, ranked/top-10 counts, net rank movement, rating), org-wide totals, biggest keyword movers both directions, a needs-attention triage list (visibility_drop / rating_drop / not_ranked signals), and the best discovered-keyword opportunities across apps. Same numbers as the /portfolio page. Requires an Agency plan — 403 on other plans. Keyword rows carry popularity, popularity_source, popularity_apple and popularity_proxy — the same values the dashboard shows (see the PopularityFields schema).
