Debug quantum campaign count/value showing 0 in front-end media buys expansion

Need to debug why quantum campaign count and dollar value showing as 0 in media buys expansion table. Webhook data is being saved correctly to database (quantum_campaigns key present, edge function 'record-webhook' saves it and sets accepted flag). Issue is front-end display - when expanding media buys to show accepted opt-ins, quantum_campaigns count and dollar value all show as 0 despite backend data being correct.
