Fix subscription screen hanging on "Loading Subscription"

The .containerRelativeFrame(.horizontal) on the marketing content
caused an infinite layout loop inside SubscriptionStoreView's scroll
container. Replaced with .frame(maxWidth: .infinity).

Also fixes leading space in StoreKit config display name, adds
debug logging to product loading, and reverts to groupID initializer.
