Subject: [PATCH] feat(attic): switch to systemd-networkd for networking

- Replace `dhcpcd` with `systemd-networkd` by setting `networking.useDHCP` to `false` and `networking.useNetworkd` to `true`.
- Add a static IPv6 configuration and routes for `enp1s0` in `30-wan`.
- Ensures a more streamlined and customizable network configuration.
