Remove the --bui-bg-popover token and adopt a two-layer background
pattern across overlay components: outer shell uses --bui-bg-app,
inner content uses Box bg="neutral-1".
Components updated: Popover, Tooltip, Menu, Dialog.
Each component gets a local border-radius CSS variable, a Box
content wrapper with neutral-1 background, and updated arrow
fills where applicable.
Story "is open" variants for each component now use a dot-grid
background pattern to detect background transparency issues in
Chromatic snapshots.
