feat: add sovran-provisioner.nix and fix headscale 0.28.0 CLI syntax in docs
- Create modules/core/sovran-provisioner.nix with Flask provisioner API,
Headscale 0.28.0 config, Caddy reverse proxy, auto-bootstrap service,
and firewall rules. Python script uses get_user_id() + -u <id> syntax.
- Fix docs/remote-deploy-headscale.md:
- nodes register now uses -u <id> instead of --user <name>
- preauthkeys create one-liner uses -u <id> -e 2h -o json
- preauthkeys list/expire updated to 0.28.0 syntax (no --user on list)
- tailscale up in Part 2 now includes --accept-dns=false
- Add Troubleshooting section: VPN conflicts, RATELIMIT logs,
connection refused, user ID lookup
