Simon Gardling ce1c335230 caddy: wildcard TLS via DNS-01 challenge + ddns-updater for Njalla ...

Build Caddy with the caddy-dns/njalla plugin to enable DNS-01 ACME
challenges. This issues a single wildcard certificate for
*.sigkill.computer instead of per-subdomain certificates, reducing
Let's Encrypt API calls and certificate management overhead.

Add ddns-updater service (nixpkgs services.ddns-updater) configured
with Njalla provider to automatically update DNS records when the
server's public IP changes.
