R-522: a disconnected tunnel is told on the dashboard row

Since v0.292.0 (R-841) cloudflared's health check asks /ready, so a lost
connection reads unhealthy; the cloudflared row now also carries the tag
"Kivulrol nem erheto el" with a plain title, in hu+en. New parity case
dashboard_tunnel_offline (born as a key).
