🤖 ci(argocd): enroll dance-lessons-coach + per-app org override in apps template

Adds dance-lessons-coach to the ArgoCD-managed gitea_applications. Extends apps.yaml template with a per-app org override (default arcodange-org) since dance-lessons-coach lives in the arcodange org rather than arcodange-org. Backward-compatible: existing apps render identically. After merge, ArgoCD will sync the chart/ folder of dance-lessons-coach into the dance-lessons-coach namespace on k3s.
