Test Port 80/443 and 32525 Outbound

sudo timeout 8 bash -c 'echo > /dev/tcp/168.63.129.16/32526' && echo "TCP CONNECT OK" || echo "TCP CONNECT FAILED"

1. Add 80,443,32526 to TCP_OUT in /etc/csf/csf.conf
2. Reload CSF (csf -r) to apply it
3. Re-verify connectivity, then restart waagent to clear its stuck retry state
