feat(cliproxy): add authentication status display to web dashboard

- Add auth status endpoint to show built-in profiles authentication state
- Display auth status in UI with visual indicators for authenticated state
- Show last authentication date and token file count
- Update CLI command to better differentiate between built-in profiles and custom variants
- Improve UI layout to separate built-in profiles from custom variants
