update_vlan now checks for vlan_id conflicts (excluding the current
record) before committing, matching the behaviour of create_vlan and
preventing an unhandled IntegrityError 500.

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).
