_bootstrap_dns runs at container start before the wizard, writing the
default cell name ('mycell') into cell.zone. When the wizard completed
it fired IDENTITY_CHANGED for Caddy but never updated the DNS zone, so
DNS records kept showing 'mycell.cell' even after naming the cell.
After successful wizard completion, call network_manager.apply_cell_name
to rename the hostname record in the primary zone file, then reload
CoreDNS. The empty old_name triggers auto-detection so it works even
when the zone was written with the env-var default.
Adds test_setup_route.py covering: apply_cell_name called on success,
not called on failure, 410 on repeat completion, and IDENTITY_CHANGED
publication.
