homebox: healthcheck must GET, not HEAD (--spider hit a 405)

With the image and the pepper fixed, homebox still sat unhealthy. The probe's own
exit code was 8 (server error response) and homebox's log shows exactly why:

  method=HEAD path=/api/v1/status status=405
  method=GET  path=/api/v1/status status=200

'wget --spider' issues a HEAD request; homebox's status endpoint only implements
GET. Switched to 'wget -q -O /dev/null' (a real GET).

NOTE: 24 templates use --spider. The rest validated green, so their endpoints do
answer HEAD -- but this is a latent trap worth a convention note (see the
campaign doc).

Campaign 7 catalog sweep.
