Add explicit handling for empty auth/whitelist arrays

When no auths or whitelists exist for a site, explicitly remove all
related htpasswd/whitelist files (including wildcards and aliases) and
return early. This makes the cleanup behavior more explicit rather than
silently iterating over an empty array.
