fix: Handle family data correctly during registration and onboarding

- Extract family data from registration response and add to user object
- Backend returns family separately in registration, but included in user for login
- Remove error messages for language/measurement preferences (they save correctly)
- Add detailed console logging for debugging family issues
- Improve error message when family is missing during child creation
