papra + wishlist: fix lying wget healthchecks (images ship only node)

Both crashes above were masking a second defect: once each app actually stayed
up, it sat permanently unhealthy because its healthcheck called wget, and
neither image has wget or curl -- only node. Traefik does not route to an
unhealthy container, so both would have served 404 to the customer regardless.

Switched both to the Node-exec family (http.get, exit non-zero on 5xx/error).

Campaign 7 catalog sweep.
