fix: restore visible borders and heading font on Card/Dialog/Select

The CLI's default style uses a very subtle ring-foreground/10 (10%-opacity
ring) instead of a real border for Card, DialogContent, and SelectContent,
which reads as invisible against our dark Hades theme. Swap to a real
border-border + shadow, matching the original PrimeVue-era design's
visible borders.

Also: CardTitle/DialogTitle/AlertTitle referenced a `cn-font-heading`
class that is never defined anywhere (dead weight from the CLI's default
style template), so titles silently fell back to the body font instead of
our --font-serif (Cinzel) heading font. Replaced with the real `font-serif`
utility. Also drops another dead class, `cn-menu-translucent`, from
SelectContent.
