Plan switching (self_serve is never offered as a switch target — see
sarvex-v1-architecture.md §Domain 8) and cancellation happen inside
this portal session, alongside payment-method and invoice management.
There is no separate checkout-based upgrade endpoint: every merchant
already has a subscription from account creation, so an upgrade is a
price change on the existing subscription — exactly what the portal's
subscription-update feature does.
