feat(node): dashboard SSE y normalización de atributos REST\n\n- Agrega dashboard web (SSE) en / con historial y eventos en vivo\n- Normaliza formato JSON de rlm_rest y registra eventos\n- Responde Access-Accept con VLAN 2 + WISPr 10/10\n\nfix(radius): corrige URI rlm_rest y acepta en lab\n\n- REST URI fija a http://node:3000 (antes expandía mal)\n- default: Auth-Type := Accept para entorno de pruebas\n- clients: añade localhost y subred 192.168.87.0/24\n\nchore: añade .env para compose
