fix(sports): send subscription to cashier queue after coach assessment

After coach assesses and assigns player to group, the monthly subscription
payment request is now sent to the cashier queue (payment_type=sports_subscription,
entity_type=sa_subscriptions). When cashier completes it, the event listener
auto-marks the subscription as paid.
