Fix Apache reverse proxy 502 error by configuring HTTP server timeouts

Set keepAliveTimeout to 65 seconds (longer than Apache's default 5s KeepAliveTimeout),
headersTimeout to 66 seconds, and requestTimeout to 120 seconds. This prevents
"Connection reset by peer" errors when using Apache2 as a reverse proxy.
