Migrar backend a PostgreSQL + Node.js/Express con nuevas funcionalidades
Backend (water-api/): - Crear API REST completa con Express + TypeScript - Implementar autenticación JWT con refresh tokens - CRUD completo para: projects, concentrators, meters, gateways, devices, users, roles - Agregar validación con Zod para todas las entidades - Implementar webhooks para The Things Stack (LoRaWAN) - Agregar endpoint de lecturas con filtros y resumen de consumo - Implementar carga masiva de medidores via Excel (.xlsx) Frontend: - Crear cliente HTTP con manejo automático de JWT y refresh - Actualizar todas las APIs para usar nuevo backend - Agregar sistema de autenticación real (login, logout, me) - Agregar selector de tipo (LORA, LoRaWAN, Grandes) en concentradores y medidores - Agregar campo Meter ID en medidores - Crear modal de carga masiva para medidores - Agregar página de consumo con gráficas y filtros - Corregir carga de proyectos independiente de datos existentes Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
