Subject: [PATCH] fix(ws): make the GeoIP database optional so a fresh clone
 starts

The GeoLite2-City.mmdb is gitignored and absent in a fresh clone, but the
reader was opened in a static initialiser, so the WebSocket controller
failed static init and the server would not start. Open it in a try/catch
and fall back to the lookup defaults when the file is missing.
