feat(odoh): relay bind-address CLI arg + dashboard Outbound Wire panel

Browse Source 
- `numa relay [PORT] [BIND]` accepts an optional bind address (defaults
  to 127.0.0.1, matching the Caddy reverse-proxy deployment shape).
  Required for Docker, where the relay needs 0.0.0.0 inside the
  container so Caddy can reach it across the bridge network.

- Dashboard now surfaces the upstream_transport dimension as an
  "Outbound Wire" panel alongside the existing "Inbound Wire" (renamed
  from "Transport" for directional clarity). Sub-headers — "apps → numa"
  / "numa → internet" — make the threat-model split obvious without
  jargon. Bars: UDP/DoH/DoT/ODoH, headline "X% encrypted outbound".
  The PR description's promise that "the dashboard answers how much of
  my DNS traffic left in cleartext honestly" is now true.
