fix(soc): trazer configs do Grafana/Promtail para o git e corrigir volumes

- Adiciona soc/promtail/config.yml (antes fora do git, em /opt/soc/) - Adiciona soc/grafana/provisioning/alerting/alerts.yml (antes fora do git) - Adiciona soc/grafana/provisioning/datasources/datasources.yml (antes fora do git) - Corrige docker-compose.yml: volumes do Promtail e Grafana agora apontam para paths dentro do repo (/home/deploy/stack/soc/) ao invés de /opt/soc/ - Corrige mount dos containers Docker: host path mapeia para /var/lib/docker/containers (path padrão que o Promtail espera dentro do container) - Corrige .gitignore: ignora apenas dados binários (grafana-data, loki-data, prom-data), não mais todos os subdiretórios do soc/ - Alertas Loki usam count_over_time() para retornar métrica numérica compatível
