Split boolean ternary endpoints into provable branches and scope payment exports.

Boolean request-param ternaries now expand into true/false binding variants so each call chain resolves a single event instead of AMBIGUOUS_WIDEN. Setter/constructor @Qualifier injection is traced for stateMachineId, and PaymentStateMachineConfig gets a dedicated golden with payment endpoints linked via paymentStateMachine.
