fix: refine proactive installation and error handling

- Remove redundant 'Command failed' message in NPM postinstall
- Use correct dashboard URL: https://dashboard.supermodeltools.com/api-keys/
- Provide explicit subscription guidance in 'status' next steps
- Display hidden input prompt during 'auth login'
