Docker Build / build-and-push-image (push) Successful in 44s
Aligns the project name with the public URL (tg.arcodange.fr) and the Arcodange organization conventions. The 'homelab-gateway' name was too generic. Touches: chart name + helpers, image registry path, Go module path, secret/configmap names, deployment mountPath, all docs.
