🐛 appsec: do not buffer unreadable (gRPC/HTTP2) request bodies (#332)

* 🐛 fix appsec silently 403-ing gRPC streams with unreadable body A bidirectional gRPC stream is an HTTP/2 request with no Content-Length whose body never reaches EOF. Since #321 removed the ContentLength guard, appsecQuery buffered it with io.ReadAll, which blocked until the request timed out and was turned into a 403 (issue #323). The backend was never reached (OriginStatus:0). Mirror the reference lua-cs-bouncer behaviour: detect an unreadable body (ProtoMajor >= 2 && ContentLength < 0) and, instead of buffering it, forward the request to Appsec with headers only. Add a new CrowdsecAppsecDropUnreadableBody option (default false) that mirrors the reference APPSEC_DROP_UNREADABLE_BODY: when true, such requests are blocked outright instead of forwarded without their body. Readable HTTP/1.1 bodies are still buffered and inspected, so the bypass closed by #321 stays closed. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * 🚨 appsec: satisfy linters (gocritic ifElseChain, misspell) Rewrite the body-handling if/else chain in appsecQuery as a switch (gocritic) and use US spelling "behavior" (misspell). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * 🔇 appsec: drop redundant unreadable-body debug log Address review on #332: the caller (handleNextServeHTTP) already logs the returned error with the request IP, so the inner Debug line duplicated it. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * 🍱 increase gocyclo * 🍱 fix lint --------- Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com> Co-authored-by: maxlerebourg <maxlerebourg@gmail.com>
