Adds the jirorian NixOS module (systemd service, sops secrets, Caddy
fragment), wires it into the flake as a Codeberg input, fixes the Caddy
glob import path, and encrypts all five R2/Nostr secrets into bucur.yaml.

Adds a webhook-deploy service that listens for Codeberg push events and
triggers per-site nixos-rebuild runs. Skips rebuilds if the flake lock
revision is unchanged. Fixes root SSH client config so nix flake update
can reach Codeberg using the existing deploy key.
