fix registry healthchecks: use 127.0.0.1 instead of localhost

Browse source 
localhost resolves to IPv6 ::1 but containers bind to 0.0.0.0 (IPv4
only), causing wget to fail with "Connection refused". The nginx
proxy had 18,462 consecutive health check failures because of this.

Also cleared corrupted pull-through cache for mghee/novelapp — the
registry had layer link files pointing to non-existent blob data,
causing containerd to get 200 responses with 0 bytes (unexpected EOF).
