Ensure Portfolio Dashboard
Idempotent: return the Commercial tab's canonical booking dashboard (the ex-Portfolio), creating + seeding it if none exists — or null when the tenant removed the tab or its built-in (PLAN-deletable-system-tabs D8; the provision ledger says it was provisioned before, so it is never recreated, and a 404 would toast on every reporting mount).
Post-kind cutover (PR5): the dashboard is identified by (category = Commercial, is_category_system_dashboard) — the partial unique index uq_one_system_dashboard_per_category makes the create race-safe (the loser retries the lookup). kind is neither read nor written here; provision_reporting_categories first migrates any legacy kind='portfolio' dashboard into Commercial.
