fix: Dashboard and NetworkServices use live domain/cell_name from ConfigContext

- Dashboard: SERVICES array (Cell Home, Calendar, Files, Webmail) now builds
  URLs from useConfig() domain + cell_name instead of hardcoded 'mycell.cell'
- NetworkServices: imports useConfig() and cellAPI; shows current DNS zone and
  DHCP range in page header; fetches service_configs.network to display
  configured DHCP range and NTP servers alongside live operational data
