Josh Knapp e4c506bcd9 PR 1/3: add coraza-spoa sidecar image ...

Self-contained sidecar that runs Coraza-SPOA v0.7.1 (latest upstream as of
2026-05-08, with OWASP CRS bundled in the binary). HAProxy will consult it
per-request via SPOE in PR 2; for now this PR ships the image only.

Defines:
- coraza-spoa/Dockerfile       — multi-stage build (golang:1.25 -> distroless),
                                 pinned to v0.7.1, ARG-overridable
- coraza-spoa/config.yaml      — single application "haproxy", JSON audit log
                                 to /var/log/coraza/audit.log, SecRuleEngine
                                 DetectionOnly globally
- coraza-spoa/overrides.conf   — day-one enforce list: scanner UAs (913xxx),
                                 RCE shell injection (932100-932160),
                                 webshell paths (933170-933200), targeted LFI
                                 (930120), Log4Shell/JNDI (944100-944300).
                                 Rationale per-range documented inline.
                                 Detect-only for XSS/SQLi/protocol (high FP
                                 on WP/WooCommerce/Divi customer mix).
- coraza-spoa/README.md        — deployment shape, audit log location, pin
                                 upgrade procedure, false-positive tuning.
- .gitea/workflows/build-push-coraza.yaml — Gitea Action triggered on
                                 coraza-spoa/** changes, publishes
                                 repo.anhonesthost.net/cloud-hosting-platform/
                                 coraza-spoa:latest. Path-scoped so it
                                 doesn't fire on every haproxy-manager push.

No changes to haproxy-manager-base itself in this PR — the existing image
stays bit-identical, used standalone in home networks and other projects
without dependency on this sidecar. PR 2 will add the OPT-IN template
plumbing that lets haproxy-manager call out to this agent when an env var
is set.
