fix: idempotent Caddy subpath config, increase Docker pull timeout to 120s, extend health check to 60s

- helpers.js: treat 'No changes to apply' as success (config already exists = idempotent)
- constants.js: Docker pull timeout 30s → 120s (large images need more time)
- deploy.js: health check 40s → 60s (some apps like filebrowser are slow to start)
