Add base text-rendering layer to v2 theme

Apply font smoothing (antialiased / grayscale) and overflow-wrap on
the document base, mirroring the root defaults Radix Themes sets.
Placed in @layer base so any utility can override it. The body font
is left to Tailwind's preflight, which already applies --font-sans.
