Fetch the current pairing code from GET /admin/paircode (localhost-only)
and display it in both the initial PairingDialog and the /pairing
management page. Users no longer need to check the terminal to find
the 6-digit code — it appears directly in the web UI.
Falls back gracefully when the admin endpoint is unreachable (e.g.
non-localhost access), showing the original "check your terminal" prompt.
