Add a "RELAY ADMIN" button to the top action bar in the Matrix workshop
UI. The button is only visible when an admin token is stored in
localStorage (relay_admin_token), linking directly to the /admin/relay
dashboard. This completes the UI integration requirement from issue #49.
The admin panel itself (auth gate, queue tab, accounts tab, stats bar)
was already implemented in admin-relay-panel.ts and the supporting API
routes in admin-relay.ts and admin-relay-queue.ts.
Fixes#49
