refactor: Kubernetes-Ressourcen und Images heissen artista-filmcamp

Alle Ressourcen tragen den Praefix artista-filmcamp- (Deployment,
Service, StatefulSet, CronJobs, PVCs, ConfigMap, Secret, Ingress,
NetworkPolicies, Middleware) und liegen im Namespace artista. Die Images
heissen wieder <owner>/artista-filmcamp und <owner>/artista-filmcamp-tools,
passend zum Repo. DATABASE_URL-Host, Backup-Host und Betriebsdoku
entsprechend angepasst.
