The dev proxy targeted 'localhost', which Node can resolve to IPv6 ::1 that the
Docker publish doesn't answer after a container recreate — every /api call failed,
spamming 'Network error'. Pin the proxy to 127.0.0.1. Also collapse bursts of
connection/5xx failures into one notification per 30s so a brief restart no longer
floods the notification center.
