feat(nix-cache): authorize pve1's wayne key as remote builder client

Generated /home/wayne/.ssh/id_ed25519 on pve1 (single-user Nix install
owned by wayne, no daemon — builds run as wayne not root). Adds the
public key to remoteBuilderAuthorizedKeys so nix-cache accepts it.

After deploying nix-cache, re-run configure-nix-cache-client.sh as
wayne on pve1 to wire in the builder line and known_hosts entry.
