Polish premium paywall sheet edge rendering

Use a borderless opaque paywall window with a sheet background color
that matches the paywall gradient so titled-window chrome does not
leave corner gaps. When presenting the sheet, size it slightly past
the host content rect with configurable per-edge overscan and an
extra half-point on the top to mask compositing hairlines.
