Open an active subscription (auto-renew on, not cancelled, the customer's current one) and click Force Renew in the header. The confirmation modal warns: "By continuing with this force renewal it will automatically charge this customer $X for this subscription. The customer will receive meals for the upcoming open delivery days." Click Force Renew to run the renewal immediately, ignoring the renewal window. The page reloads on success; on failure you see "Error: ..." with the payment or setup problem. The action is logged as triggered by your admin account.
