When a VLAN/LAN is deleted, all non-gateway, non-livebox devices
with an interface in that network are deleted automatically.
Gateway and livebox devices are preserved; their interface is
unlinked (vlan_id set to NULL).
The confirmation dialog now shows the exact count of devices
that will be deleted (all three locales: fr/en/es).
