List Subscriptions Route
GET/v1/subscriptions
Paginated subscription-product list. Optional ?category= filter.
?category=bogus produces a 422 validation_error before
any DB round-trip (the whitelist check runs in the service
layer's list_subscriptions, which raises ValueError that
the generic handler maps to 422).
