/.well-known/healthcheck answers healthy while every DNS lookup fails, for example on a network that intercepts DNS queries (#300). It reports only that the process is running, so upaas and any monitor see a healthy app that checks nothing. Noted by the reviewer of #301; it was already so before that PR.

Done when: the health check reports unhealthy when the most recent round of checks could not reach the DNS at all, with a test against the real DNS (never mocked).

Model: opus-5-5
