Add user tag editing and improve member error display

- Display actual error message in member detail page instead of generic Member not found
- Add debug logging to user.get query to help diagnose issues
- Add expertise tags editing for users in profile settings page
- Update user.updateProfile mutation to accept expertiseTags
