Zero uploaded files causes the "All Files" page to return 500

This page returns a 500 if there are no files to display: https://urcpp.berea.edu/committee/allFiles

Open https://urcpp.berea.edu/committee/allFiles with no uploaded files and reproduce the 500 response. Trace the page's entry point and the handling of an empty file list, then verify that the page loads successfully and presents an appropriate empty result instead of an error.
