[BUG]: Active sidebar navigation item is unreadable due to light background #568

Affected Module

Core / Admin Panel (Filament sidebar navigation)

What happened?

The active menu item in the Admin panel sidebar renders with a white/light-gray background (var(--gray-100)) applied by the Filament class .fi-sidebar-item.fi-active > .fi-sidebar-item-btn. The panel uses the Nord theme which has a dark sidebar, so the light background makes the active item's text and icon unreadable — white text on a near-white background.

Expected: The active sidebar item is clearly highlighted and its label remains readable against the dark sidebar background.

Actual: The active sidebar item shows a --gray-100 background which clashes with the dark Nord theme, making the text invisible.

Steps to Reproduce

1. Log in to the Admin panel (/admin)
2. Observe the sidebar — the currently active navigation item has a washed-out appearance
3. Inspect the element — it has class fi-active and the rule .fi-sidebar-item.fi-active > .fi-sidebar-item-btn { background-color: var(--gray-100); } is being applied
