All host port bindings in docker-compose.yml now use \${VAR:-default} substitution,
driven by the .env file generated by ip_utils.write_env_file(). Changing a port in
Settings triggers a per-container pending-restart banner so only the affected container
is restarted on Apply.
- ip_utils: add PORT_DEFAULTS, PORT_ENV_VAR_NAMES, PORT_TO_CONTAINERS; extend
write_env_file() to accept optional ports dict and write all port env vars
- docker-compose: convert all hardcoded port bindings to \${VAR:-default} form
- app.py: add _collect_service_ports helper; detect port changes in update_config,
write updated .env and call _set_pending_restart with specific container list;
update _set_pending_restart to merge/accumulate pending state with containers list;
update apply_pending_config to use --no-deps <service> for targeted restarts
- config_manager: add submission_port, webmail_port to email schema; add manager_port
to files schema
- Settings.jsx: make all email/files ports editable, add submission_port, webmail_port,
manager_port fields; update stale identity note
- tests: 8 new tests for PORT_DEFAULTS, PORT_ENV_VAR_NAMES, and port override in write_env_file

config_manager restore_config and import_config previously injected zero-filled
entries (port=0, domain='') for every service schema regardless of whether that
service was in the backup/import data. Removed this logic — only restore what's
actually in the backup.
network_manager.apply_domain now:
- updates dnsmasq.conf domain= line (reload cell-dhcp)
- rewrites Corefile zone blocks to the new domain name
- renames and rewrites the primary zone file $ORIGIN + SOA records
- reloads CoreDNS
Tests added first (TDD):
- test_restore_does_not_zero_unconfigured_services
- test_restore_does_not_zero_import
- test_apply_domain_updates_corefile (zone file + Corefile)
- test_apply_domain_updates_dnsmasq
- test_apply_config_writes_dhcp_range / ntp_servers
- test_apply_config_updates_mailserver_env / no_domain_no_restart
