ActivityEventType

Event types visible to the partner (feed and webhooks). church.onboarded arrives once per church, the first time the church becomes ready for paycheck giving: the same moment payout_ready turns true on GET /v1/churches/{id} and GET /v1/churches. If the church later stops being ready, no event is sent; read payout_ready. Churches that were already ready before Roster started sending church.onboarded do not receive it. Today it is sent in the sandbox only; in production, read payout_ready.
