feat(transfer): add DELETE endpoint, domain events, and event-driven Typesense sync

- DeleteTransferListingCommand/Handler with seller authorization and soft delete (→ CANCELLED)
- Domain events: TransferListingCreated/Updated/DeletedEvent with EventEmitter2
- Event handler: TransferListingTypesenseHandler syncs Typesense on all CUD operations
- Create/Update handlers now emit domain events after persistence
- DELETE /transfer/listings/:id controller endpoint with JWT auth
