feat: regenerate models with preauth events and transaction_id fix

Regenerated from OpenAPI spec. Adds PreauthCreatedEvent,
PreauthApprovedEvent, PreauthRevokedEvent to the Event discriminated
union. Fixes crash when the events API returns preauth events.

CreateRequestResponse now includes optional transaction_id from the
spec (present when preauth auto-confirms).
