Resolves plan item A.1 (option б): login/setup rate-limiting used RemoteAddr only, which behind the default reverse proxy is the proxy's own address, making the limiter effectively global and enabling a lockout-DoS. Now, when the request's direct peer matches the new TRUSTED_PROXY_CIDR list (comma-separated CIDRs, env, empty by default), the last X-Forwarded-For entry is used instead, giving a real per-client limit. Unset behaviour is unchanged. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
