fix(flowiseai): ensure setup_nodejs is called before updating FlowiseAI

- Use pnpm add -g instead of npm install -g (apify-client enforces pnpm)
- Call setup_nodejs to ensure pnpm is available in existing containers
- Migrate ExecStart from 'npx flowise start' to 'flowise start' in
  existing installations on update
