Show all connected Tailscale peers with connection methods

Replace single connection method display with individual sub-service
rows for each online Tailscale peer. Each peer shows hostname and
connection type (direct, relay, or idle) allowing monitoring of all
connected devices and their connection quality.

Query tailscale status --json to enumerate all online peers and display
each as a separate sub-service under tailscaled.
