- Live file preview on all file inputs (file-field partial, edit template):
thumbnails for images, emoji icons for PDF/video/zip/vtt, filename + size
- New file-preview.js wired via $extraJs in add.php / edit.php and direct
<script> in partage/index.php; $extraJs support added to head.php
- admin/recapitulatif.php: replace plain table with rich file list — image
thumbnails linked to media.php, type badges, human-readable size, date
- partage/recapitulatif.php: full rewrite — shows thesis metadata + files
list with same rich display (no media links for student privacy)
- form.css: new sections for .file-preview-list (live preview) and
.recap-file-list / .recap-dl / .partage-recap (recap pages)
