Fix wildcard-parent edit greying and deprecated nginx http2 directive

- The edit form's "Parent Wildcard" option stayed greyed out even when a
  valid wildcard existed, since hostEditOpen() never ran the eligibility
  check (only the host field's keyup handler did, which setting .val()
  programmatically doesn't fire) -- and the check itself, GET
  /host/lookup/:item, had the same self-match bug as the recently-fixed
  Host.prototype.update() case: it resolves an already-existing host to
  its own record instead of a sibling wildcard. Added a dedicated
  /host/wildcard-parent/:item route combining lookUp() (handles a
  brand-new subdomain) with lookUpWildcardParent() (handles an
  already-existing host), and hostEditOpen() now actually runs it.

- Migrated ops/nginx_conf/autossl.conf's deprecated "listen ... http2"
  directive to the standalone "http2 on;" directive (nginx 1.25.1+).

Bumps to v1.1.12.
