Fix port forwarding: read file instead of HTTP API, fix server names

- portforward-helper now reads /tmp/gluetun/forwarded_port via shared emptyDir
  volume instead of polling gluetun HTTP API (which returned Unauthorized)
- Main qbt: SERVER_NAMES=US-IL#1 (valid entry in gluetun server list)
- Both manifests cleaned up
