The generic rate-limits are tuned high for media-heavy sites, so slow
credential-stuffing on wp-login.php slips under them. Add a dedicated sc1
stick-table (backend wp_bruteforce, 60s window) that counts POSTs to
wp-login.php per real client IP and tarpits once an IP exceeds 30/min.
Only login POSTs are counted (browsing + the login form GET + a legit user's
few attempts are unaffected); an offending IP can still browse, just not keep
hammering login. Honors the existing whitelist (RFC1918 / trusted_ips.list /
trusted_ips.map) and the already-resolved CF/proxy real IP. path_end also
covers subdirectory WP installs. Stops attacks at the edge before they reach
PHP/WordPress, on all edges regardless of Coraza mode.

HTTP/3 is config-only — the Debian haproxy package is built +QUIC via the
OpenSSL compat shim. Changes:
- hap_header.tpl: `limited-quic` (required to enable QUIC binds under the
compat layer) + self-healing `cluster-secret` for QUIC token derivation.
- hap_listener.tpl: `bind quic4@:443 ... alpn h3` in the shared frontend (so
real-IP/rate-limit/IP-block/Coraza rules apply to H3 too) + alt-svc header.
- Dockerfile/README: publish/document 443/udp; stamp image.version from VERSION.
- CI: tag :latest + :<VERSION> + :<sha> so there's a pinnable rollback target.
No 0-RTT (compat-layer limitation). Validated end-to-end on a standalone edge:
config parses, UDP/443 binds, alt-svc advertised, real curl --http3 -> HTTP/3.
Container must run with `-p 443:443/udp` + host UDP/443 open.
