fix: TFE and annexes files not saved, plus keyword validation and file preview CSS

- ThesisCreateController::submit() was missing call to handleAnnexeFiles
- ThesisEditController::save() was missing annexe upload handling
- handleAnnexeFiles now applies ALLOWED_MIME_TYPES/ALLOWED_EXTENSIONS validation
  (same restrictions as TFE files, formerly only size was checked)
- Use correct $_FILES key 'annexes' (matching the form input name)
- Relax keyword minimum: admin create/edit require 1+, student (partage) requires 3
- Add CSS styles for file preview items (.fp-item, .fp-thumb, .fp-icon,
  .fp-meta, .fp-name, .fp-size) so multi-file previews (annexes, etc.) wrap correctly
- Fix TFE file input accept attribute in fichiers-fragment.php to include
  video/audio/archive extensions
