v1.4.0 — Mise à jour firmware hors-ligne par upload ZIP

Nouvelle fonctionnalité permettant de mettre à jour le firmware sans
connexion internet, via upload d'un fichier .zip depuis l'interface admin.

Fichiers ajoutés:
- update_firmware_from_file.sh (rsync + exclusions + chown + restart services)
- .update-exclude (liste d'exclusions évolutive, versionnée)
- html/.htaccess (limite upload PHP 50MB)

Fichiers modifiés:
- html/launcher.php (handler upload_firmware)
- html/admin.html (UI upload + barre de progression)
