yusing c8d7d4f7d3 refactor(acl): memoize IPAllowed with goutils keyed TTL cache ...

Replace the xsync map plus manual expiry on checkCache with
cache.NewKeyFunc(evaluateIP).WithTTL. Move deny/allow/default logic into
evaluateIP; wire getCachedCity and IPAllowed through the cache API.

Refresh README security notes and add tests showing cached decisions persist
across in-memory rule changes until TTL expires.
