fix(ui): suppress native focus outline on dialog, alert dialog and sheet panels

Radix focuses the content element (tabindex="-1") when a dialog opens, and the panel had no
outline suppression, so Chrome drew its default blue focus-visible ring around the whole panel.
Adds focus:outline-none to the dialog, alert dialog and sheet content base classes. Interactive
children keep their themed focus rings.
