feat(ui): show internal hostname and densify config UI

Add an application Internal access section that loads the running
container hostname (skipped for Compose apps), densify configuration
diff and popup-small defaults, dock the server-timing HUD into the
mobile top bar, restyle the 2FA challenge with the auth shell, and
enforce 16px mobile form fonts to prevent iOS zoom.
