Adds viewportFit: 'cover' so the PWA can draw under the notch /
Dynamic Island when installed. Nav and Toast read env(safe-area-inset-*)
to keep their content out of the hardware cutouts (no-op on browsers
without a notch — env() resolves to 0).
Replaces autoFocus on the first field of CreateAccountDialog and
CreateUserDialog with a useEffect that only focuses on pointer devices
(matchMedia '(hover: hover) and (pointer: fine)'). Phones no longer
get the soft keyboard popping the instant a dialog opens.
