[bojemoi] fix(grafana): adapter Docker Container metrics — name→id, cAdvisor v0.55

Commit `023fe7e`

cAdvisor v0.55 n’expose pas container_label_* dans Prometheus metrics
Remplacement name=~~".+" → id=~~"/docker/[a-f0-9]+" (filtre containers réels)
Remplacement by (name) → by (id) dans tous les panels
Suppression variables Prod/NonProd (IPs hardcodées 10.115.x.x inexistantes)
prometheus.yml: relabeling container_label_com_docker_swarm_service_name→name (préparatoire)
stack: revert flag –allowlisted_container_labels (non supporté v0.55)
