nixos/systemd: Temporarily bring back multi-user -> network-online

There were several modules, critically including NetworkManager, which
were not prepared for this change. Most of the change was good,
however. Let's bring back the dependency and change the assertion to a
warning for now.

 - `services.avahi.nssmdns` got split into `services.avahi.nssmdns4` and `services.avahi.nssmdns6` which enable the mDNS NSS switch for IPv4 and IPv6 respectively.
   Since most mDNS responders only register IPv4 addresses, most users want to keep the IPv6 support disabled to avoid long timeouts.

 - `services.archisteamfarm` no longer uses the abbreviation `asf` for its state directory (`/var/lib/asf`), user and group (both `asf`). Instead the long name `archisteamfarm` is used.
   Configurations with `system.stateVersion` 23.11 or earlier, default to the old stateDirectory until the 24.11 release and must either set the option explicitly or move the data to the new directory.
