After the static IP change, k3s/flannel pod networking broke because ip_forward was 0. NixOS doesn't enable IP forwarding by default — it was previously being set implicitly somewhere in the NM-managed / scripted-DHCP path. With static networking we have to set it ourselves. Verified at runtime via sysctl -w before adding here; pod outbound came back immediately and Tailscale VIP services recovered without any pod restarts.

Pin ringtail's wired IP to `192.168.1.21` via NixOS scripted networking; NetworkManager no longer manages `enp5s0`. Removes DHCP lease renewal as a failure mode after a silent lease teardown took ringtail offline. Also explicitly enables `net.ipv4.ip_forward` (previously set implicitly by scripted-DHCP) so k3s pod networking and Tailscale routing continue to work with static networking.
