• Added loading indicators and disabled action buttons while API requests are in progress.
• Improved the Admin Submissions page by:
  • Displaying human-readable submission dates.
  • Adding status filtering.
  • Showing loading states during data fetching.
  • Adding tooltips for truncated notes.

• Verifying submission access for both authorized and unauthorized users.
