feat: Add Docker Compose monitoring stack with Prometheus, Grafana, InfluxDB, Redis, node-exporter, and Alertmanager

- Add Prometheus service with 9090 port, 200h retention, lifecycle API enabled, prometheus_data volume
- Add Grafana service on port 3001, admin password, sign-up disabled, provisioning and dashboards volumes
- Add InfluxDB 2.7 with 8086 port, telecom org/bucket, admin credentials, influxdb_data and influxdb_config volumes
- Add Redis 7-alpine service on port 6379 with redis_data volume
