[REST: `POST /v1/trips/{tripId}/commercial-state`](https://api.bymundi.com/docs/reference/trips.setCommercialState.md)

## What the model reads

Moves the trip's commercial state (nueva, propuesta_enviada, aceptada, reserva_provisional, reservada, rechazada, cancelada), as the state menu does in the app. Any state may move to any other. ⚠️ This has side effects and no undo. Entering `reserva_provisional` or `reservada` creates payment plans for accepted quotes. Entering `reservada` opens the travelers' app access, which emails them. Asking for the state the trip is already in changes nothing.

Permissions: trips:write.
This cannot be undone.
