Subject: [PATCH] fix(native): a store account with a running TREK Cloud
 subscription buys no second one

One subscription per Apple ID or Google account. Choosing another plan in the app changed the running subscription on the App Store, and the redeem then failed with 'We could not set up your TREK'. The app now asks the store first and shows a screen of its own: the account already has TREK Cloud, a new one can be taken out once it has ended, with Open my TREK and the store's page to manage it. The native purchase refuses as well; a paid one that was never set up is still redeemed. On the address screens the link 'What is a TREK server?' is gone, and the small print under a purchase is set in the system text face at regular weight.
