Org Get Billing
Get organization billing summary.
Every role gets the same balance + payment-terms, because the client spending guard (computeBillingBlocked) reads them and must behave identically for everyone — sending a message bills the org wallet regardless of who posts it. Over-redacting these from members (returning only role + usage) made the task composer default account_balance to 0 and compute a false “balance depleted” block, hard-stopping members from sending on a fully funded org. Members still don’t get the payment-method management surface (Stripe ids, billing email, saved cards, auto-reload): topping up / changing payment settings stays owner-only and is enforced on those endpoints.
