Backend logging:
- Log channel, sub-channel, and proof type counts in get_all_hierarchical()
- Log Meta proof types specifically
- Log API response for Social.Meta
Frontend logging:
- Log raw API response in apiService
- Log dropdown options in App.tsx when loaded
- Log available proof types in UploadProofModal when channel/subchannel selected
This will help diagnose why Meta proof types are not appearing on staging.
