feat(crm): Cotizaciones/Cotizador vinculados (Fase B)

- Lista de cotizaciones muestra la Solicitud referenciada (QuoteResponse enriquecido
  con service_request_reference; columna con enlace a la solicitud).
- Cotizador vinculable a una solicitud (?service_request_id=) → prellena modo
  (mapper transport+load→RateMode), ruta, peso/dimensiones, etc.
- Cotizador vinculable a una cotización (?quote_id=) → botón "Agregar" por opción
  que crea el concepto de flete + cargos en la cotización y regresa a ella.
- Botón "Cotizador" en el detalle de la cotización (entrada vinculada).

Suite de cotizaciones en verde. svelte-check sin errores nuevos.
