fix(status): show model_list entries and fallback chain in status command

- Display model_list entries with their model strings and API endpoints
- Show the full fallback chain (primary + fallbacks)
- Check model_list for API keys/bases in addition to legacy providers config
- This fixes the status command showing 'not set' even when model_list is configured
