feat: add GitHub Actions deploy workflow + SSL config

- GH Actions workflow: build 3 Docker images → push to GHCR → SSH deploy
- Host nginx configured with Cloudflare Origin SSL (port 443)
- HTTP→HTTPS redirect on host nginx
- SSL certs excluded from git via ssl/.gitignore
- Container nginx/ports unchanged (internal only)
