fix(settings): fix latency ping and tunnel auto-reconnect defaults

- Default latencyPingEnabled to false so badges are hidden until opted in
- Fix toggleLatencyPing sync condition from !== false to === true to match
  the new default correctly
- Default tunnelAutoReconnect to true so tunnels reconnect automatically
  out of the box
- Hide latency badges in virtual hosts and service tunnels tables when
  latency ping is disabled
