Fix publish state tracking and add sync status feature

- Track moderation status (pending/approved/rejected) in local tool config
- Add new "pending" state indicator (◐ yellow) distinct from "published" (✓ green)
- Add "Sync Status" button to check registry for updated moderation status
- Add /me/tools/<name>/status API endpoint for checking tool status
- Improve admin panel error handling with better error messages
