fix(monitoring): dashboard infra — remplace regex instance par job=node-exporter

Browse source 
instance=~"192\.168\.10\.(11|12|13):9100" → job="node-exporter"

La barre oblique inversée dans les regex PromQL string literals causait
une erreur "unknown escape sequence" (\.  n'est pas un escape PromQL valide).
job="node-exporter" est équivalent (seuls les 3 compute nodes ont ce job)
et ne dépend pas d'adresses IP hardcodées.
