feat: TypeScript bastion rewrite (initial scaffold)

Full rewrite of the bash bastion.sh into a TypeScript application:
- Fastify HTTP server with typed routes (dispatch, kickstart, API)
- Commander CLI (serve, install, list, reprovision)
- Kickstart templates as TypeScript template literals (no more heredoc hell)
- dnsmasq management via execa subprocess
- Merged machine list view (hardware + install info in one table)
- Containerized via podman-compose (Dockerfile + docker-compose.yml)
- All partition logic preserved (LVM, reprovision detection, role-based)

Not yet tested end-to-end — needs VM validation before replacing bash version.
