* feat: Allow cache reading from replicas
* 🍱 fix logic
* ✨ add testing for redis with mock
* 🍱 fix permission
* 📝 test(e2e/redis): fix swapped IP→verdict comments
The mock returns "f" (not banned) for 1.2.3.4 and "t" (banned) for
1.2.3.5, and the run.sh assertions match that. Both doc comments
described the opposite mapping; correct them to match the code.

* ✅ test(e2e/redis): exercise read-from-replica path
The redis scenario only set redisCacheHost, so it validated the writer
but never the round-robin reader path this feature adds. Split the mock
into two roles: the primary (--redis-addr) now answers every GET with a
miss, while the replica (--redis-read-addr) serves the hardcoded
verdicts. The scenario points redisCacheReadHosts at the replica (twice,
to drive round-robin), so the banned-IP-blocked assertion only passes if
the plugin actually reads decisions from the replica rather than the
primary.

* 📝 docs: note replicas don't fall back to primary on outage
When RedisCacheReadHosts is set, reads are not retried against the
primary if the replicas are unreachable. Document that this, combined
with the default RedisCacheUnreachableBlock=true, means a replica outage
can block traffic while the primary is healthy.

* 🐛 fix(cache): avoid nil-pointer panic on empty redis read
redisCache.get fell through to `switch err.Error()` when Get returned a
nil error with an empty value, panicking on the nil error. simpleredis
never returns that combination today (a miss yields RedisMiss), so it
was unreachable in practice — but the read path is safer treating an
empty, error-free read as a cache miss, which also guarantees err is
non-nil before err.Error() is called.

* 🐛 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.

* 🚨 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).

* 🔇 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.
