The Caddyfile was bind-mounted as a single file. ansible.builtin.template writes
atomically (temp + rename), so a re-render swaps the file's inode while the running
container keeps the old one — `caddy reload` then re-read stale config and silently
no-op'd ("config is unchanged"), so new routes never loaded. Surfaced deploying the
NetBird route: Caddy never requested its cert. Fix: render to ./caddy/Caddyfile and
mount the ./caddy DIRECTORY at /etc/caddy — directory mounts reflect inode swaps, so
graceful `caddy reload` works. Proven on askari: atomic replace in the host dir is
visible inside the running container.
