Two HAProxy parse errors caught in staging functional test:
1. coraza-spoe.cfg:39 'args': missing fetch method
The args directive had backslash line continuations. HAProxy doesn't
support those in SPOE configs — args must be one physical line.
Collapsed to a single line.
2. coraza-spoe.cfg:50 Missing LF on last line
Same trailing-LF issue we hit on haproxy.cfg one commit ago. The
Jinja2 template ends with content rather than a newline, and write()
doesn't add one. Belt-and-suspenders: explicitly append '\n' before
writing if not already there.
After this commit HAProxy validates the generated config cleanly. Will
verify on staging now (combined SPOE injection + fail-open + active
attack-detection tests).

Adds the plumbing that lets haproxy-manager talk to the coraza-spoa sidecar
added in PR 1, while keeping the default behavior bit-identical for any
deployment that doesn't set the new env var (the home network / standalone
use cases).
Single gate: HAPROXY_CORAZA_SPOE_BACKEND env var on the haproxy-manager
container. Unset (default) = generate_config() renders zero SPOE-related
output. Set (e.g. "coraza-spoa:9000") = three things happen at config
generation time:
1. hap_listener.tpl injects 5 lines at the end of the frontend block:
filter spoe engine coraza config /etc/haproxy/coraza-spoe.cfg
http-request send-spoe-group coraza coraza-check
...placed AFTER rate-limit and IP-block guards so we don't waste WAF
calls on requests we were going to drop anyway.
2. A new TCP backend (hap_coraza_spoa_backend.tpl) is appended:
backend coraza-spoa-backend
mode tcp
server coraza-spoa <env-var-target> check ...
3. The SPOE engine config (hap_coraza_spoe_engine.tpl) is rendered and
written to /etc/haproxy/coraza-spoe.cfg, defining the spoe-agent
"coraza" + spoe-message "coraza-check". This sets:
- option set-on-error continue (FAIL-OPEN if SPOA is unreachable)
- timeout processing 100ms (per-request inspection budget)
- app=str(haproxy) (matches sidecar's application name)
Verification (template render only, before staging deploy):
- hap_listener.tpl with no env var: 55 lines, zero SPOE references
- hap_listener.tpl with env var: 62 lines, filter + send-spoe-group present
- Engine cfg + backend block render with correct agent_target substitution
Next: PR 3 wires this into WHP (sidecar deploy via container-manager.sh
extension, server-settings UI for on/off, AI Monitor source for the audit
log). Staging verification of PR 1 + PR 2 together happens after PR 3.
