Each service manager now has apply_config() that writes to the actual config:
- network: dhcp_range → dnsmasq.conf (reload cell-dhcp), ntp_servers → chrony.conf
(restart cell-ntp), domain → dnsmasq.conf domain= line
- email: domain → mailserver.env OVERRIDE_HOSTNAME + POSTMASTER_ADDRESS,
restart cell-mail
- wireguard: port/address/private_key → wg0.conf ListenPort/Address/PrivateKey,
restart cell-wireguard
- calendar: port → radicale config hosts=, restart cell-radicale
PUT /api/config now calls apply_config() after persisting JSON, and returns
{restarted: [...], warnings: [...]} so Settings UI can show which containers
were restarted. _restart_container() helper added to BaseServiceManager.
