Warn when network selection was skipped instead of making it mandatory

Replace the mandatory network_config menu requirement with a yellow
warning on the final confirmation screen, shown only when the user
skipped the network menu entirely. Explicitly picking "No network
configuration" is treated as a conscious choice and does not trigger
the warning.

- Drop mandatory=True from the network_config global menu item
- Rename NicType.NONE menu label from "No network" to
  "No network configuration" (an installed system still has an NIC;
  only the install-time configuration is absent)
- Add ConfigurationOutput.get_install_warnings() and render them in
  confirm_config when show_install_warnings=True
- guided.py and minimal.py enable the warning on the confirm screen
- Reuse the existing "No network configuration" msgid in .pot; add the
  warning string; update Ukrainian translations accordingly
