[A11Y] Missing `aria-label` on interactive buttons across multiple files

Hello! The <button> elements in several files lack aria-label attributes, making it difficult for assistive technologies to determine their purpose. Affected files include:\n- src/components/DropdowndetailsPage.tsx\n- src/components/StatisticDetails.tsx\n- src/components/Stories.tsx\n- src/components/CalendarDetails.tsx\n- src/components/NavigationDetailsPage.tsx\n\n### Proposed Approach:\n1. Identify buttons in the affected files that need accessible names.\n2. Apply appropriate aria-label attributes.\n3. Verify tab accessibility.\n\nI would love to take this on for GSSoC '26. Could you please assign this to me?
