Subject: [PATCH] fix(ui): VK-iOS shows the pack CTA disabled with a toast, not
 a failed buy

Money purchases are not permitted in the VK iOS app (Apple ToS), and the backend
already refuses them (the CreateOrder VK-iOS freeze). Show the pack "Buy" muted
there and explain on tap ("purchases are not available on this platform"),
instead of letting the tap hit a 403 and a generic error toast. The storefront
still lists the packs.
