install_appliances_from_image relied on the name+version pair check in TemplatesService, so the same appliance reached through a second image (the CSR1000v case) created a second template sharing the name. The auto path now skips when any template with the same name exists, whatever the version, and returns a manifest of created and skipped candidates; POST /images/install replies 200 with that manifest instead of an empty 204, and the image_install MCP tool surfaces it.
