Summary of PR

This PR fixes an accessibility violation in the Sidebar component by adding a descriptive aria-label attribute.

Demo Screenshots/Videos

The patch submitted in this PR was generated by A11YRepair, an automated Web Accessibility repair tool that I developed to address common accessibility violations in web applications.
The generated fixes were manually reviewed and validated before submission.

Reasoning Process of A11YRepair:

Based on the A11Y Bug Report and WCAG Guidelines, the <aside> element, which has an implicit ARIA role of "complementary", is missing an accessible name. This makes it difficult for screen reader users to understand the purpose of this landmark region and navigate the page effectively.

To fix this, I will add an aria-label attribute to the <aside> element to provide a descriptive label, such as "Sidebar". This will satisfy the requirement for landmarks to be labeled, as outlined in WCAG 2.4.1 and demonstrated in techniques ARIA11 and ARIA6.

Here is the patch to fix the violation:

### /frontend/src/components/features/sidebar/sidebar.tsx
<<<<<<< SEARCH
      <aside
        className={cn(
          "h-[54px] p-3 md:p-0 md:h-[40px] md:h-auto flex flex-row md:flex-col gap-1 bg-base md:w-[75px] md:min-w-[75px] sm:pt-0 sm:px-2 md:pt-[14px] md:px-0",
          pathname === "/" && "md:pt-6.5 md:pb-3",
        )}
      >
