The other vhosts (gitea, grafana, search, ...) now use username 'dankuser'
with CADDY_BASICAUTH_HASH, which is set to the same hash as the homepage
(dankpassword.123). So the whole protected surface logs in as
dankuser / dankpassword.123; the operator /admin/ page still uses frank.
Updated the two tests that asserted the old 'dank' username.
