How geovanesv/backend-reservas-nest works

This NestJS backend provides event, reservation, and user operations. The principal domain flow is creating a reservation: the reservation service looks up the event, checks and increments its capacity count, then saves the reservation. Event and user CRUD are additional capabilities. The graph also shows the shared application wiring and persistence layer. Some controller and module excerpts were unavailable, so those connections are omitted rather than inferred.
