feat(deliverynote): snapshot clínico (ExtraInfo) desde presupuesto

Se implementa la construcción automática de ExtrainfoJson al seleccionar un presupuesto en la pantalla de emisión de Delivery Note.

- Se genera snapshot clínico con Professional, Institution, Patient y SurgeryDate
- Se serializa a JSON plano utilizando System.Text.Json
- Se asigna a Model.ExtraInfoJson para persistencia
- Se limpia el snapshot al deseleccionar o fallar la carga del presupuesto

Se mantiene consistencia con el patrón implementado en Expeditions.
No se modifican contratos ni capas Core/API/Data.

Closes #41
