fix: restore Steam master query reliability and disable startup auto-refresh - Improve Steam Web API master query request handling: - trim trailing '\0' from filter before sending - URL-encode API key and filter parameters - try both GetServerList endpoint variants (/v1 and /v0001) - Keep server list parsing resilient for current API response formats. - Reduce web request timeout to 8s to avoid long “Requesting...” hangs on failure. - Stop auto-calling ReloadServerList() during form startup; refresh is now user-triggered.

- handle the case when there is no GeoIp provider
