Subject: [PATCH 2/2] Free plan: use $0 PaymentIntent instead of SetupIntent
 for age verification

All plans now use the same payment intent flow. Free creates a $0 PI
with payment_method_types[]=card and setup_future_usage=off_session.
No charge, card saved. Removes setup_mode=true for free plan.

Fix submit button label: show 'Verify age & get started' for free
instead of 'Complete purchase'. Retire checkout-free.el.
