**Native (Play / App Store):** the app buys through StoreKit or Play Billing,
then `POST /api/finance/store/confirm/` with the signed App Store transaction
or the Play purchase token. The backend verifies it (Apple certificate chain,
or Play Developer API `purchases.subscriptionsv2`) and upserts the ledger.
`source` is `app_store` or `play_store`. There is no store webhook. Renewals
are another confirm from the app; access ends when `current_period_end` passes.

**Native (Play / App Store):** RevenueCat webhooks at

`UserSubscription` (`source=revenuecat`).
