Agregar endpoints proxy para evitar CORS entre subdominios

- /api/streams/list: proxy a streams.nucleoriofrio.com/api/streams
- /api/frigate/event: proxy a camaras.nucleoriofrio.com/api/events
- Actualizar composables para usar los proxies del backend
- Los iframes de streaming siguen usando URLs directas (sesion propia)
