Agregar proxy para clips y snapshots de Frigate

- Crear /api/frigate/events/:eventId/clip con soporte de range requests
- Crear /api/frigate/events/:eventId/snapshot
- Usar IP interna 192.168.87.29:5000 para evitar autenticacion Authentik
- Actualizar URLs en useFrigateEvents para usar proxies internos
