Fix API authentication - set g.user_id in auth decorators

The /api/wallet endpoint was returning 401 because it checks g.user_id
but the auth decorators only set request.current_user. Now both are set.

- Fixed require_auth decorator in auth.py to set g.user_id
- Fixed get_api_auth_decorator in routes.py to set g.user_id
