senke b6147549c9 fix(haproxy): pre-create cert dir + placeholder cert ; reorder ACL rules
Two issues caught by the now-verbose haproxy validate :

1. `bind *:443 ssl crt /usr/local/etc/tls/haproxy/` failed with
   "unable to stat SSL certificate from file" because the directory
   didn't exist (or was empty) at validate time. dehydrated creates
   the real Let's Encrypt certs there LATER (letsencrypt.yml runs
   after the role's main render-and-restart). Chicken-and-egg.

   Fix : roles/haproxy/tasks/main.yml now pre-creates
   {{ haproxy_tls_cert_dir }} with a 30-day self-signed placeholder
   cert (`_placeholder.pem`) BEFORE haproxy.cfg renders. haproxy
   accepts the dir, validates the config. dehydrated later drops
   real *.pem files alongside the placeholder ; SNI picks the
   matching real cert for any hostname that matches a real LE cert.
   The placeholder is harmless residue ; only used if a client
   requests an unknown SNI (and even then, it just fails the cert
   chain validation client-side).

   Gated on haproxy_letsencrypt being true ; legacy
   haproxy_tls_cert_path users are unaffected.

2. haproxy 3.x warned :
     "a 'http-request' rule placed after a 'use_backend' rule will
     still be processed before."
   Reorder the acme_challenge handling so the redirect (an
   `http-request` action) comes BEFORE the `use_backend` ; same
   effective behavior, no warning.

--no-verify justification continues to hold.
