Drop NicType.NONE from this PR

The NONE option introduced earlier in this branch is being removed per
review feedback (#4408). Whether to add explicit "None" options across
multiple menus (greeter, gfx driver, network, bootloader) is now being
discussed in #4464 and should land as a separate change there.

This PR keeps only the warning-on-confirm behaviour: when the user
skipped the network menu entirely (network_config is None), a yellow
warning is shown on the final confirmation screen.
