Fix Starface JSON parsing and Outlook folder/contact reading

Starface API:
- Handle both array and object responses from /contacts endpoint
- Try common wrapper fields (items, contacts, data, results)

Outlook contacts:
- Add FindFolderByPath that matches exact FolderPath property
- Fallback to Namespace.Folders navigation if store lookup fails
- Fallback: try reading contact fields even if Class != 40
- Add debug logging for folder path and item count
