/**
 * After Google turned the Fitbit Web API off, a Fitbit connection that has
 * gone quiet is the provider's shutdown, not a broken pipe. Against real
 * Postgres: the health read publishes no state for it (so no card or banner
 * asks for a reconnect), the watchdog pages nobody, and the connection row
 * and every imported reading stay.
