fix(menu): update hover color variable to use the correct reference (#7544)

* fix(menu): update hover color variable to use the correct reference

Medium Severity

In the horizontal .is-light menu section, --menu-item-hover-color is set to hsl(var(--menu-item-color)), but --menu-item-color is already defined as hsl(var(--accent-foreground)). This results in hsl(hsl(...)) at computed-value time, which is invalid CSS. The non-horizontal .is-light block correctly uses var(--menu-item-color) without the extra hsl() wrapper.

* fix(menu): simplify hover styles by removing redundant nested hover rules

Low Severity

The SCSS &:not(.is-active):hover { &:hover { ... } } compiles to a :hover:hover pseudo-class chain, which is functionally identical to a single :hover. The inner &:hover nesting is redundant and adds unnecessary complexity compared to placing styles directly inside the &:not(.is-active):hover block.
