feat(reports): per-NRL Data Files tab reaches parity with the project-wide tab

The per-NRL Data Files tab now reuses the same FTP browser + unified-files partials as the project-wide tab, scoped to the one NRL: ftp-browser and files-unified take an optional location_id. nrl_detail.html drops the flat file_list view for 'Download Files from SLMs' (Browse Files -> Download & Save) plus the grouped 'Project Files' view (edit times / download-all / delete), keeping the NRL upload and adding a refresh button.
