consultoria-as 5a913dcac1 feat(monitoring): add Grafana dashboards for PostgreSQL, Redis, System, App
- nexus-postgresql.json: connections, transactions, cache hit, WAL,
  slow queries, table bloat
- nexus-redis.json: memory, commands/sec, clients, cache hit,
  keyspace hits/misses, evicted keys
- nexus-system.json: CPU, memory, disk, network, load average
- nexus-gunicorn.json: request rate, response time, workers,
  5xx errors, memory per worker
- dashboards.yml: auto-provisioning config
