Unify hover effects via semantic theme tokens

Replace one-off hover colors with hover-neutral/hover-destructive tokens
so all interactive elements respond consistently to theme changes. Fix
hover-neutral-bg token value (was identical to card surface, making hover
invisible on card backgrounds) to a semi-transparent primary tint. Switch
turn nav buttons to outline variant for visible hover feedback. Convert HP
popover damage/heal to plain buttons to avoid ghost variant hover conflict
with tailwind-merge.
